I swapped iPhones with my husband and now I have gone from a 3gs to a 3g. I restored from a back up and switched sim cards. Everything worked fine except my apps and music from iTunes will not sync. I did the same process with my husband's phone and his music and apps synced just fine. The sync is very short and not music, photos, or apps go back on my phone. Any ideas on what might be wrong or how I can fix this? Thank you in advance for the help!
