3GP and 3G2 are container formats similar to MPEG-4 Part 14 (MP4), which is also based on MPEG-4 Part 12.
After 18 months of negotiations, Steve Jobs reached an agreement with the wireless division of AT&T to be the i Phone's exclusive carrier.
Consumers were unable to use any other carrier without unlocking their device.
At that time, instead of focusing on a follow-up to their Newton PDA, Jobs had Apple focus on the i Pod.
Jobs also had Apple develop the i Tunes software, which can be used to synchronize content with i Pod devices. On September 7, 2005, Apple and Motorola released the ROKR E1, the first mobile phone to use i Tunes.
3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services.
