IPhone sync issues causing frustration?

My iPhone won't sync with my PC itunes and does without any problem with Mac which is not mine. Its a 4s I just bought and all the other iPhones do sync without any problem.
No matter I select to sync contact with google contacts, outlook contacts are synced. It's also happening on PC.

Look up your problem on apple website (http://www.apple.com/) or use the support helpline (http://www.apple.com/support/contact/)

  • What is causing my iPhone bill? Hi, i'm getting pretty big iphone bills at the end of each month, and i don't know why. I've turned data roaming off, and my contract says i have unlimited calls, texts and data usage. Any suggestions as to what it is thats causing these charges?
  • What could be causing my sore heads and dizziness? I'm 17 years old and I basically spend everyday on my iPad, laptop, iPhone or watching tv. I don't exercise and I don't have a good diet. Every time I stand up I get dizzy and have a head ache. And if I run up the stairs or run a little distance I feel faint. My mum is trying to make me get a blood test but I'd rather have an idea of what's wrong first. Could it be from spending too much time looking at screens or lack of exercise?
  • What could be causing my iPhone to not be holding a charge? It's an iPhone 4, and I've had it a few months short of two years. I've taken good care of it, it's got plenty of memory, updated software, I'm not running many apps (I double click the home button to close them often), but my phone's battery won't last at all lately even when I don't use it very often.
  • Iphone 4s exiting out of apps and causing other trouble? My iphone recently has been exiting me out of apps and just not working. My messages take forever to send and i'm not recieving some messages at all. I believe this all began after the newest update. My phone is practically full and I have used all 16 gigs and i'm not sure if thats the reason. I looked under diagnostics and usage and "backupd" is what it says almost all of the time. I would like to know if this is a software issue or an issue with the actual phone.
