This is really a major advancement for the iPhone platform. With 3.0, you have many different calendar synchronization options and can mix and match, using all or none as you see fit:

How to Subscribe to a CalDAV Server (Like Google Calendar)

CalDAV is a powerful open protocol for calendar event synchronization. Lots of services support it, including Google’s free Calendar application, which is part of gmail and Google Apps. It’s a mash-up of WebDAV and ICS and supports two-way synchronization, notes, alerts, and such. iPhone OS 3.0 includes CalDAV as a supported protocol for over-the-air subscription and synchronization, so it can seamlessly synchronize your Google calendar with your phone calendar. Unlike ICS, however, you can create and edit CalDAV entries on the phone and the changes will quickly show up in your Google calendar.

iPhone 3.0 includes direct over-the-air use of CalDAV, ICS, and LDAP servers

Setting up CalDAV, though hidden, is pretty slick. Follow these steps:

1. On the iPhone, select “Settings”
2. Select “Mail, Contacts, Calendars”
3. Select”Add Account…” under “Accounts”
4. Select “Other” at the bottom
5. Select “Add CalDAV Account”
6. Enter “www.google.com” for “Server” – the iPhone will automatically identify this as a google CalDAV server!
7. Enter your gmail user name (e.g. “sfoskett”) or full google apps username and domain (e.g. “stephen@fosketts.net”) for “User”
8. Enter your password for “Password”
9. Optionally modify the description
10. Select “Next” and you’re done!

The iPhone recognizes Google Calendar – it’s smart enough to “know” that when you enter “www.google.com” as the CalDAV server it needs to correctly format the URL for Google. Other CalDAV server types might need some tweaking, which you can do in the Advanced tab of the CalDAV’s account in Settings.

All CalDAV calendars are bi-directional, meaning you can create or edit entries and they will (eventually) synchronize on both the phone and calendar server. In my tests, items modified on the iPhone showed up almost immediately, while changes made on Google’s calendar server took a few minutes to show up.

Two notes on CalDAV:

1. Although the documentation says it’s read-only, my Google Calendar absolutely, definitely, is read/write: I can create and modify appointments in the Google Calendar on the iPhone and it shows up online.
2. The “Sync events x weeks back” limit in settings does not apply to CalDAV or ICS! Large numbers of events will cause Calendar to be very, very slow. Beware!

Other popular apps also support CalDAV, including Apple Leopard Server’s iCal Server, Yahoo Calendar, and Zimbra.

I use this capability as a shared family activities calendar. What ideas do you have?

How to Subscribe to an iCalendar Server/.ICS feed

iCalendar is an older calendar subscription format, and many servers offer .ICS feeds of calendar entries. I particularly love TripIt‘s free travel itinerary service, which is available as an ICS feed. iPhone OS 3.0 also includes iCal as a supported protocol for over-the-air subscription, so you can view your ICS feeds right in your phone calendar. Note that iCalendar is read-only, like an RSS feed, so you cannot create or edit items on the phone.

Tap a link to a .ics file and the iPhone will ask to subscribe

The simplest way to subscribe to an ICS feed is simply to email the link to yourself. The iPhone interprets any URL ending in “.ics” as a iCalendar feed and asks if you want to subscribe. This ensures that the link is typed correctly.

Note: This no longer works in iOS 4.2! Now you have to add it in Settings. See Apple Breaks ICS Calendar Auto-Subscription In iOS 4.2.

If you need to manually set up an iCalendar feed, it’s very similar to CalDAV. Follow these steps:

1. Locate the calendar feed you want to use and copy it using OS 3.0′s new copy and paste features
   1. If you use TripIt, log into your account in the iPhone Safari browser
   2. Select the “iCal Feed” icon in your main page
   3. In the popup, select “Subscribe to calendar feed”
   4. Tap and hold the resulting URL (which begins with “webcal://”) until the “Copy” box appears
   5. Tap “Copy”
2. Go back to the hope screen and select “Settings”
3. Select “Mail, Contacts, Calendars”
4. Select”Add Account…” under “Accounts”
5. Select “Other” at the bottom
6. Select “Add Subscribed Calendar”
7. Select the “Server” box and tap “Paste”
8. Select “Next”
9. Optionally modify the description

Updates to the iCalendar feed will now show up in your calendar. These are read only, of course, but it’s awfully nice to be able to subscribe to a TripIt or Dopplr feed or the Red Sox schedule on your phone!

One more time: The “Sync events x weeks back” limit in settings does not apply to CalDAV or ICS! Large numbers of events will cause Calendar to be very, very slow. Beware!

IT infrastructure is following consumer technology out of the data center glass house and into the wide world

Dave Hitz over at NetApp poses a very interesting question: What is the ten-year trend in information technology that we are currently building to? He supplies these historical examples:

• 1982-1992: A computer on every (business) desk
• 1990s: Networking all those computers

He then goes on to suggest three ten-year trends that we might currently be living through:

1. Cloud/Outsourced Computing
2. Server Virtualization
3. Flash Memory

Although I agree on the importance of these three to enterprise IT, I don’t think they’ll be seen as the megatrends of this decade in hindsight. I suggest that, more than anything, we are witnessing a wholesale shift from information tied to place/device to information mobility. Cloud computing, server virtualization, and even flash memory are all contributors to this massive trend, along with the user-side trends of the post-PDA mobile phone, 3G data, social web services, and connected home.

What Is Mobility?

The meaning of mobility, to me, is expansive. It doesn’t just refer to taking a copy of your data with you, ubiquitous connectivity, or portable devices. Mobility is a new paradigm of computing.

• Your data no longer “sits” in one place – your data lives out there in the network!
• Your applications no longer “live” on this device or that – your applications live out there in the network!
• Your productivity environment no longer requires a particular piece of hardware – you expect to be productive everywhere on every device!

This doesn’t sound strange to the modern Internet user. We have completely accepted the role of Google, Facebook, Yahoo, Wikipedia and the rest in our personal lives. Just as they did in the early days of the PC, business people have transitioned these concepts into the professional world – witness Salesforce and LinkedIn! In all cases, we have endorsed the idea that certain types of information want to live in the cloud because it makes them better!

Once you’ve used these services, old-fashioned email, contact management, encyclopedias, maps, and the rest seem incredibly limiting. A GPS system that can’t update its maps seems antiquated, and we want it to have real-time traffic data, too. An iPod that needs to be physically connected to a PC to add music or applications is simply unacceptable. Time- and place-shifting technologies like TiVo To Go, over-the-air podcast downloads, and Slingboxes reset our expectations about availability and choice of entertainment, but they are mere symptoms of our changing perceptions. We want mobility of data, applications, and platforms, and we are getting it.

Consider two truly revolutionary platforms: the iPhone and the netbook. In both cases, we knowingly accept limitations in the name of portability, knowing that the cloud will give us what we can’t hold in our hands. These devices are limited in ways that would seem inconceivable just a few years ago: Apple has locked their platform up tighter than any in history, and netbooks are too small, underpowered, and cheap in all senses of the word. But we love them because they get us where we want to go, which is up and out!

Mobility and Enterprise IT

The concept of mobile data, applications, and devices is just as applicable to enterprise IT infrastructure as it is to personal technology. Some enterprise data must be kept close to the vest, especially where privacy laws and litigation concerns are applicable. But there is certainly a vast pool of corporate data that wants to be out working in the field! Setting this data free is the enterprise equivalent of the mobility megatrend!

Cloud computing is hype. Server virtualization is hype. Flash storage is hype. XaaS is hype. Web 2.0 is hype. But once the cloud of hype passes, we will be left with solid technologies to enable mobility and transform corporate computing. Why should corporate email have to punch through your firewall? Why should the intranet be limited to internal or VPN users? Why can’t customers interact with a (limited/controlled) set of your corporate records? Salesforce showed us that roaming users (sales teams) need greater access than most IT staff were ready to build. What if we applied the same ideas to other data types?

Many companies are already doing this. Microsoft offers a variety of internal/external services for their customers through Live (see Connect, for example). Many companies are using mail and productivity applications in the cloud from Google, MessageOne, and Zimbra. Backup and archiving as a service to mobile users is widespread (see Iron Mountain Connected and Mozy). And more and more corporate PR relies on blogs, twitter, and social networking sites. Corporate security and legal types are worried about data “escaping” from the eggshell of control they exert, but this cat is out of the bag. Enterprise IT will never be the same!

It comes down to a single core question that IT folks ought to have been asking themselves all along: What should be held internally and what should be let loose? We already “outsource” many non-core corporate functions. Sometimes we do this for cost reasons. But the most effective outsourcing decision is when a third party will do a better job, offering levels of expertise or service that an internal group could never realistically reach. We already buy enterprise software to leverage outside development (remember, this was not always the case!), so why not also buy enterprise services? Corporate-grade outsourced email, groupware, sales automation, and the like is not only more robust and less expensive than internal systems, they enable a disconnected, mobile workforce.

Today, I Was Angry

I bought a new album from Amazon, but I forgot to sync my iPhone with my laptop, so it was sitting at home when I wanted to listen to it in the car. Then I couldn’t find a colleague’s phone number because he moved to a new company and my address book didn’t automatically update. And I couldn’t review a presentation because I needed a special account to access a corporate document system behind a firewall.

These little accomplishments would have seemed like miracles just a few years ago: I remember the joy I felt ten years ago when I could read a web page offline on my Palm Pilot using AvantGo; I was amazed when I first fired up 802.11a wireless networking and could work anywhere in the office; I was gleeful to be able to take 5 GB of music with me on the train. But all this is past. Today, I want to access my portable data and work anywhere. We are in the midst of a revolution in the mobility and ubiquity of computing.

The iPhone doesn't support more than one Exchange/ActiveSync pairing

One of the major advances introduced in iPhone software version 2.0 was the ability to sync over-the-air to Microsoft Exchange servers using Microsoft’s ActiveSync protocol. This was introduced to much fanfare with the iPhone 3G and is available on older updated iPhone and iPod Touch units, too. Google and NuevaSync also offer over-the-air calendar and contact syncing for the iPhone using ActiveSync.

All of these synchronization options seem like an embarrassment of riches for iPhone users. But, like so many things in life, they’re too good to be true. iPhone OS 2 and 3 can’t sync to more than one Exchange/ActiveSync server at a time! Or, at least, not in the way you’d like.

Note: iPhone OS 4.0 will allow syncing to multiple Exchange ActiveSync accounts! See How To Set Up Multiple Exchange ActiveSync Accounts in iPhone iOS 4.

For the most up-to-date information, see my iPhone Exchange ActiveSync Guide!

2. Can the iPhone Sync With Multiple Exchange Servers?

The Connected iPhone

Let’s back up a minute and talk about how the iPhone integrates with mail, contact, and calendar servers. There are essentially two synchronization engines at work here:

• Like all iPods, iTunes can synchronize your contacts, calendars, and mail account information (though not the mail messages themselves) over a USB connection to the iPhone and iPod Touch. This requires a full copy of Outlook 2003 or later on Windows but works with the built-in address book and iCal calendar on Mac OS X.
• The iPhone can also synchronize some or all components of email, contacts, calendars, and bookmarks using a variety of over-the-air protocols.

Note that when you configure over-the-air sync, you must disable USB sync, and vice versa.

iPhone Email Sync

Configured mail accounts can synchronize email messages in one of six ways:

1. Periodically pulling message content down using the POP protocol – this is what most older ISPs and mail accounts use
2. Periodically pulling message content down using the more advanced IMAP protocol – this is what newer mail accounts, including Gmail, AOL, and Yahoo use
3. Having mail pushed to the phone using a weird combination of hidden SMS and IMAP – this is what Yahoo push mail uses
4. Having mail pushed to the phone using a proprietary notification system of XMPP (Jabber) and IMAP – this is what Apple’s MobileMe push mail uses
5. Pulling or receiving push messages using Microsoft’s ActiveSync technology – this is what Exchange servers, NuevaSync, Kerio, Zimbra, and Google’s over-the-air calendar and contact (but not email) sync use
6. The iPhone’s software seems to support IMAP Idle, which is a realtime message push technology supported by Gmail and some advanced mail systems, but the phone will not use it unless the mail application is actually open on the phone

The iPhone does not support P-IMAP, BlackBerry, or other over-the-air protocols at this point.

The iPhone can sync email messages to any number of IMAP or POP accounts without a problem, but it can only sync to a single ActiveSync server at once. So you can set up Gmail over IMAP, Yahoo over SMS/IMAP, your local provider over POP, a Gmail Apps account over IMAP, etc at the same time as your work Exchange server without a problem. But you cannot set up more than one Exchange server using ActiveSync.

iPhone Calendar and Contact Sync

Calendar and contact information can only be synced in one of (perhaps) three ways:

1. Over a physical USB connection to iTunes (as in the original iPhone 1.0) to Outlook or OS X
2. Using some unknown protocol that MobileMe uses – can anyone identify this?
3. Using ActiveSync to an Exchange Outlook Web Access (OWA) server

Yes, that’s really it. Every over-the-air calendar-and-contact sync system (other than perhaps MobileMe) uses the ActiveSync protocol, including Microsoft Exchange, NuevaSync, Zimbra, and Google’s service.

Now the punch line: The iPhone can only sync to a single ActiveSync server at once. Read that again. Now consider what that means.

So no matter how cool a service is (Google sync, Zimbra), you cannot use it for over-the-air sync if you are also connected to an Exchange server. So even though the iPhone explicitly supports multiple calendars, you can’t sync them with multiple ActiveSync systems. So I guess the iPhone’s calendar system is even more disappointing than I thought!

Pick One ActiveSync Service

The upshot is this: iPhone users much pick one (and only one) ActiveSync service.

• Need to use the iPhone for work? You’ll probably have to use your work Exchange ActiveSync server, and can forget about (usefully) subscribing to MobileMe or using Google sync. Instead, try to sync everything else into Exchange in other ways (like Google’s Desktop app) and then let Exchange handle the iPhone sync.
• A dedicated Mac head? Subscribe to MobileMe and get all of your data there, to be sent to the iPhone.
• None of the above? Google’s new Sync service looks great!

The Big Mystery

There are many mysteries lurking here, but one is really perplexing to me. The iPhone seems to maintain its own set of contacts in addition to any ActiveSync contact store. Although it doesn’t obviously have multiple contacts pools, it must maintain them internally. But you can see that it does in a simple way:

1. Set up an ActiveSync server (like Exchange)
2. Set up an IMAP email account (like Gmail)
3. Add a unique contact on the phone (call him “Steve Jobs”)
4. Add a unique contact in Exchange (call him “Bill Gates”)
5. Add a unique contact in Gmail (call him “Sergey Brin”)
6. Now turn on and off the accounts one at a time

Notice that turning off the Gmail account will, within a few minutes, cause your “Sergey Brin” contact to disappear! Turn it back on and Sergie is back. Now do the same for Exchange and Bill Gates. All the while, your “Steve Jobs” contact should stay put. And this all happens in a single contact list! If you assigned one of these to a “favorite”, their name will be replaced by their number when you remove their account.

So the is iPhone somehow syncing contacts over IMAP? Or does it use some other Google-specific protocol? And how does MobileMe’s contact sync work? Time will tell!
