I have 2 phone numbers, one on ATT with iPhone, one on Verizon that I'm upgrading to an iPhone this week (currently it's not a smart phone). Can I move the apps and music from the old phone over to the new one? I only need one number and it makes more sense to keep the Verizon one. I think the apps are attached to my iTune account rather than my phone so it seems like it would be possible.
