So I got the new iPhone 4s and I want to backup my data from my i4.  I click to backup my 4, and it starts the backup but then just stops in the middle of it.  It stops anywhere from around 5% done to 90%.  I've let it sit for a couple hours and it hadn't moved since I had left.  Is there anyway to fix this?  I really don't want to lose my app data, texts, have to retype all my contacts, and reconfigure my home screen.  Thanks for any help in advance.
