Many of us have been watching Apple's WWDC 2008 keynote unfold live. There are many exciting tidbits, but most of all is the announcement of the 3G iPhone. Featuring an even thinner profile, black plastic back, metal buttons, flush headphone jack, improved audio, GPS support, and improved battery life, this is bound to make quite a few people stand up and take notice. Update 18:54 GMT by SM: Best of all it looks like they really took the price point to heart, 8GB iPhones are now $199 and a 16GB model will be available for $299, coming to an Apple store riot near you on July 11,2008.
