UGH I'm ready to throw my phone out the window!

I updated the Facebook app on my iPhone 4, and it sat there "loading" forever, so I went back to the home screen, deleted it, and reinstalled it from the app store. But then as it was in the "installing" phase, the phone stalled, and became unresponsive. So after ~5 minutes, I forced restart (hold down both power and home buttons for a few seconds). NOW I'm getting the freaking "Wire ==> Itunes" picture! WTF!! Its been so long since I backed up to my laptop, I really don't want to restore if I don't have to. Is this happening to anyone else?? I saw others were having issues on the iPhone 4... What gives?
Any suggestions or solutions?
