Hey guys, I gifted my brother an iPhone 5 have a tracking number with it and he can't wait for it (neither can I)! Thing is, he's moving from an iPhone 4 to the iPhone 5, so how would I activate the iPhone 5 since there are two different SIM cards? I read earlier on here somewhere you simply turn the device on and the older iPhone/device gets deactivated. Is this true? Thanks everyone! I'm glad to be part of such a wonderful community!
