My sister is visiting and her iPhone 3GS fell out of the diaper bag. The screen is cracked so badly that the phone won't work. I have an old 3G laying around to give her until she is able to get home and get a new phone. Normally when you sync contacts from one iPhone to another, all you have to do is back-up the first phone and restore the 2nd from the back-up. However, the 3G isn't giving her this option. I'm guessing that it is b/c she is going to from a new phone to an older phone. Is there a way to transfer her contacts and calendars from the newer phone to the older phone?
