The first solid info anyone heard about the iPhone was in December of 2004, when news started to trickle out that Apple had been working on a phone device with Motorola as its manufacturing partner.
The new Apple iPhone 2.0 firmware offers some nice improvements for business users, including Exchange Active Sync support, as well as the new App Store.
It's hard to think of any other device that's enjoyed the level of exposure and hype that Apple found in the launch of the first iPhone.
There's a reason why Apple called this the iPhone 3GS for Speed and not the 3GC for "compass" or 3GV for "video recording."
Apple's launch of the iPhone 4 has seen the greatest excitement for a new phone ever - and with HD video recording, a super high-res screen and ridiculously slim dimensions, it's not hard to see why.
