Apple officially announce iPhone 4 yesterday at the Worldwide Developers Conference (WWDC) 2010. I have been following it live on GDGT which I think is the fastest when compared to Engadget. This time round Gizmodo is just aggregating news as I think they are not physically there maybe because of the leak?
MicroSIM is now being used instead of the normal SIM card which is the same case as the iPad. Camera has been bumped up to 5MP with LED flash, front-facing camera added and Apple calls that FaceTime which is a nicer word for video conferencing except that it is for WiFi only. HD video recording at 720p, screen resolution has been increased to 960-by-640-pixel resolution at 326 ppi, Three-axis gyroscope is added. Processor has been bumped up to 1GHz using the same Apple A4 chip found in iPad. For more details, check out the Design Page of iPhone 4.
