If its beyond repair, try using iExplorer to rip everything off of your iPhone and restore to a new iPhone and put everything you've ripped off of your iPhone back in

Just be sure you use iExplorer, as willerz suggested above, before restoring as a "New device." iExplorer will give you root access to your iPhone and allow you to pull pics, ringtones, music, contacts, etc. from it and allow you to drop it into iTunes on another computer.
