I was wondering if there was a way to connect a Verizon phone to At&t or cricket or any other network? Or an At&t iphone with another network? I have a friend that just came back from africa and is going back again and he knew a couple people that wanted the iphone but use it on one of their networks over there? He was saying something like that if you have the unlock codes you could change networks even if it was a Verizon/At&t? I looked around a little bit and think these codes are called sublock codes? im not sure though. But which got me thinking, if you can root the phone or jailbreak whatever, is there a way to install the software to match that of At&t or another network? I have no idea, im just asking?
