To a booming applause Steve Jobs unveiled the long awaited iPhone 2.0 at WWDC 2008.

As expected it is now 3G, has GPS support, the App Store for downloading applications and games over the air. Among the examples on Apple's site there's a Twitter client poking out. They must know something we don't, as an army of tweeting iPhone users isn't going to help Twitter's currently overloaded state.

To keep the corporates happy, enterprise support for Microsoft Exchange via ActiveSync. For non Exchange users who want to keep up to date, there's MobileMe, which promises to keep calendars, contacts, etc all nicely synced across devices. It doesn't look like there's any SyncML support but given the conflict with MobileMe that's hardly a great surprise. I hope I'm wrong.

The headphone jack is no longer a headache, and you can use any standard 3.5mm headphones directly with the iPhone 2.0. Good thing as the sound quality has been much improved. The unit is also thinner, has metal buttons, a black plastic back and somewhat more oomph from the battery.

Extremely welcome was the fact they've knocked the price from the speculated $399 to a much more affordable $199 (USD). With that and the fact they're allowing iPhone 1.0 owners to upgrade the phone software, it would be fair to guess Apple are trying to get enough market penetration to head off the impending arrival of Google Android based phones.

Alas as it's not out until July we won't know if one can perform the same jailbreak tricks. We've waited this long so what's another month? ;)
