Steve Jobs has just announced the new iPhone 3G at WWDC 2008. Apple’s new phone features fast 3G wireless technology, GPS mapping, support for enterprise features like Microsoft Exchange, and the new App Store.

Apple claims its 3G speeds trounce the competition, with pageloads 36% faster than the N95 and Treo 750 — and of course it completely trounces the old EDGE data. Battery life isn’t getting put out to pasture though, with 300 hours of standby, 8-10 hours of 2G talk, 5 hours of 3G talk, 7 hours of video and 24 hours of audio.

iPhone 3G will be released on July 11th in Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Mexico, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, UK and the US.

The price is $199 for 8G and $299 for the 16GB model.
