Back up your iPhone and then jailbreak it again.
After jailbreaking it again, restore the Data.
If it does it again, you need to start from scratch because either you or someone (or maybe a file) changed most you Data from what it was (music, video, photos etc...) to Other.
Its gonna suck if you have to do everything over again, but its probably because they are placed in the wrong folder due to a failed jailbreak, or you pulled the cord while jailbreaking.
