How to Remove Other Data on iPhone?

I'm sure many people have had this problem, but I have a 16GB iPhone 4S that has 13.56GB of usable data but ends up with 3GB of that taken up by what is "Other" data. I managed to reduce it from 4GB by restoring and then using a backup, but its still a ton of data being used up. I can't take photos or have all the music I want on my phone. Any help?

Your other data would be photo's or browser history. Next time you restore your phone set it to sync manually. Remove all your photo's, and anything else you might of installed. Let everything get removed from your phone. The only thing that should be in other is your contacts. After that you can manage your storage better.
