Swapping iPhones with my GF
Ok, I've seen a few questions that are simular to mine. I have an iPhone 4 she has an iPhone 4s and we want to switch (ya there's some money involved lol). From what I understand what I'll have to do is back up each iPhone on each respective computer that it's synced to then restore (wipe) each iPhone then switch sim cards then restore the iPhone 4s with my computer and the 4 with hers. Is it really that simple? Will all the apps including the medical app that she had to put in a product code for transfer to the other iPhone?
Thanks in advance for the help,
