At Apple’s annual Worldwide Developer Conference (WWDC) in San Francisco, Steve Jobs introduced a brand-new iPhone: the iPhone 3G.

Features include:

• 3G speed ( 3x faster internet connection)

• Built-in GPS (with live tracking, no turn by turn)

• Thinner design

• Cheaper ($199 for 8GB, $299 for 16GB)

• Microsoft Exchange support (push e-mail, contacts, etc. with ActiveSync)

• Available July 11

Jobs also introduced MobileMe, a service that syncs any change you make on one device with all your other devices. For example, if you change a contact or a calendar date on your iPhone, that change will be immediately reflected on your two other laptops.

Finally, Jobs said that they will be showing some new features of 10.6 Snow Leopard, a new version of Apple’s operating system that is in the works. Developers will get a peak later today at WWDC.

Personally, I think the new iPhone looks pretty slick. However, I was hoping there would be some more significant features than just 3G and GPS. If you are as nerdy as me, you know that the internet predicted those features in the next iPhone long ago. Will the new iPhone cause me to purchase a new one right away? Probably not. Will it help Apple sell more iPhones? With the cheaper price, definitely.
