How to easily switch iPhones?

The link above shows the details, but basically here's what happens:


Back up the old one

Erase the "new" phone to factory defaults

Setup new phone from backup

Power up the phone you want to transfer to and see what version of iOS it is running. You'll more than likely need to upgrade that before you can restore the other phone to it. So power on, connect to wifi and update the os to whatever version the other phone has. then reset all settings and put the phone you want to transfer to it next to each other and bluetooth should connect all do the transfer. You can do a backup and restore as well. Many ways to do it.
