Swapped iPhones with my husband and now apps and music won't sync! Any help?

[dwine10]

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!

Deauthorizing and reauthorizing the computer in iTunes should fix it.

Any chance your new phone isn't set to sync?

Next time you plug it in, in iTunes, click on the phone, then check the individual tabs for their sync settings.
