3GP - is the new mobile phone video file format.
3GPP, 3GPP2 are the new worldwide standard for the creation, delivery and playback of multimedia over 3rd generation, high-speed wireless networks. Defined by the 3rd Generation Partnership Project and 3rd Generation Partnership Project 2 respectively, these standards seek to provide uniform delivery of rich multimedia over newly evolved, broadband mobile networks (3rd generation networks) to the latest multimedia-enabled wireless devices. Tailored to the unique requirements of mobile devices, 3GPP and 3GPP2 take advantage of MPEG-4, the standard for delivery of video and audio over the Internet.

Extensions:
.3gp 3GPP standard, GSM Network, Video: MPEG-4, H.263, Audio: AAC, AMR
.3g2 3GPP2 standard, CDMA2000 Network, Video: MPEG-4, H.263, Audio: AAC, AMR, QCELP.
