3gp downloads – why?
3GP or .3gp is the third generation video standard. It integrates mp3, mp4, 3gpp, 3g3p and 3g2. 3GP is a multimedia container format defined by 3GPP for use on 3G mobile phones. It is a simplified version of MP$). 3GP files have the filename extension .3gp or .3g2.

3GP also describes image sizes and bandwidth, so content is correctly sized for mobile display screens.

3GP files are also viewable on a PC using programs like QuickTime or RealPlayer.

iPhone and some higher-spec video phones like the Nokia N Series can handle larger sized MP4 files. These are also available at Share on Ovi, but I provide all my videos in iPhone compatible mp4 / m4v format here on Twittervlog.tv
