ITunes other memory problem?

I have a 16GB iPhone 4s and it is jailbroken (don't remember the stuff i used for it though) i have 3.3GB of music (430 songs or so) 3.1GB photos (218 pic/vids) 2GB apps 4.9 Other and.42GB free. How do i remove the 'other' without restoring my phone and such? Also it is version 5.1.1

Oh wow i had the exact same issue.

i got my new ipad 4 2 weeks ago and guess how frustrated i was with this issue… Didn't happen when i used the iphone 4.

i solved it by removing some photos and videos, and… Most importantly RESETTING network settings.

that removed around 5GB of the 'other' bit i had.
