Make sure your Itunes & Iphone have latest updates. Apple has updated 3 times since February and it can mess up sync. Update your computer first (under Apple logo - "software update") then log onto Itunes and update Iphone

If you forgotten the pass-code on the iphone, usually the only option is to restore the iphone.
By default, Itunes is not going to give you the option to restore when you plug your iphone in. What you will have to do is to put that iphone in recovery mode.
Restoring your iphone will delete everything on your iphone! -Hold down the top button and the home button of the iphone together until you see a silver apple logo -when you see the silver apple logo let go of the top button of the iphone and keep holding on to the bottom button of the iphone until you see a usb plug with an up arrow going into itunes -plug into itunes and it will detect a phone in recovery mode -click ok -click restore -click restore and update
I Hope this Helps! Good luck!
