Everything you need to know about Apple's 3G networking, GPS-packing, second-generation iPhone 3G
At WWDC 2008 on June 9, after finalizing the details of the upcoming App Store, and summing up the original iPhone's achievements, the late Steve Jobs dove into the next challenges Apple had to face, the next mountain they had to climb. On the surface, they were obvious even before Jobs bulleted them on stage - 3G (+ GPS), Enterprise, third-party apps, more countries, and more affordable - $199/$299 on contract. The software changes came as part of iPhone OS 2.0. The hardware, iPhone 3G.
Code-named N82, version number iPhone1,2, and models number A1241 and A1324 (China), Apple dropped the iPhone 3G price to $99 in 2009, and it was discontinued in June of 2010.
