How to fix my iPhone without restoring it?

I went to settings on my iPhone and installed the iOS 6 software. After the installation it restarted. The apple logo appeared and it stayed like that for a really long time. I've tried turning it off and putting it back on but no luck. The only thing I can do is to restore it but if I do everything that I didn't back up will be gone. My last backup was like 3 months ago. I never connect it on the computer only when I need to backup. What can I do?

Added (1). If I go to the apple store, will they be able to fix it? Can they make my iPhone back to normal? I didn't turn on photo steam so my photos are not backup.
