ok i've worked out an easier way to transfer gopro videos (if you have a pc) and without needing to use itunes - works on fully ios version (no need to jailbreak)
1. copy mp4 from gopro to your computer.
2. download i-funbox classic (
http://dl.i-funbox.com/ifunbox_classic.zip ) extract, and run.
3. make sure phone is connected.
4. Browse to user apps - harry laptimer - documents
5. Click copy from PC - browse to the gopro mp4 and will copy across.
6. Go into harrys laptimer, click on relink, and the gopro mp4 will now show with a red ! next to it, click on link and done
