Sim Card Problem/Jailbroken 1.1.2 downgraded problem
So i have a new 1.1.2 week 49 iphone. I downgraded it so i could activate. My problem is every sim i go to buy so i can use my iphone on any GSM says it requires the phone to be re-upgraded but then i lose my activation.
I was wondering what sim i should buy to make my 1.1.2 downgraded to 1.1.1 jailbroken able to use any GSM or is there a way to activate/GSM unlock a 1.1.2 without downgrading.
Im really sorry if there is a thread on this but i've read literally 100s of threads trying to find a answer.
