3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones.

3G2 (3GPP2 file format) is a multimedia container format defined by the 3GPP2 for 3G CDMA2000 multimedia services. It is very similar to the 3GP file format, but has some extensions and limitations in comparison to 3GP.

3GP is defined in the ETSI 3GPP technical specification. 3GP is a required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia Broadcast/Multicast Service (MBMS) and Transparent end-to-end Packet-switched Streaming Service (PSS).

3G2 is defined in the 3GPP2 technical specification.

The 3GP and 3G2 file formats are both structurally based on the ISO base media file format defined in ISO/IEC 14496-12 - MPEG-4 Part 12, but older versions of the 3GP file format did not use some of its features. 3GP and 3G2 are container formats similar to MPEG-4 Part 14 (MP4), which is also based on MPEG-4 Part 12. The 3GP and 3G2 file format were designed to decrease storage and bandwidth requirements in order to accommodate mobile phones.

Nathaniel Joseph "Nature" Ruess (February 26, 1982) is an American indie/indie pop singer-songwriter from Arizona. Ruess was the singer of The Format and currently lead vocalist of the band Fun.

Nate was born February 26, 1982 in Iowa City, Iowa. He was the youngest of two children, his sister Libbie being one year older.

In 1986, his family moved to a farm in Glendale, Arizona, where he remained throughout his childhood. He attended Deer Valley High School and graduated in 2000. Having an uncle, John Ruess, who performed on Broadway, Ruess was always somewhat interested in music and performing. He joined punk bands in high school and, upon graduation, chose to pursue music instead of attending college. He never took formal singing lessons or learned to play an instrument and was often told by peers that he lacked the talent to make it professionally. He took a job in a law firm as a way to support himself while he pursued his musical ambitions.

In 2001, at the age of 19, he launched the band The Format with his longtime best friend, Sam Means. This was his first musical endeavor to garner widespread attention.
