Help! iPhone 4 activation no SIM
Alright guys. I have no clue what I'm doing so be kind, please.
I bought an iPhone 4 5.0.1from Amazon Warehouse. The description said it has been unlocked with Gevey SIM but it came without a SIM card in it. I have TMobile and read online that I can cut my regular SIM card down to micro and use it in an unlocked iPhone.
The problem is, now, I can't activate it or get anywhere because I don't have a compatible SIM card. I tried to jailbreak it using redsn0w but i can't get my iPhone to turn off and therefore can't put it into DFU mode. I also don't know my firmware version and so far the 112 call and firmware call aren't working.
I tried to use pwnage tool but I don't know my firmware version and nothing I download will work. I also tried to install my choice of firmware on iTunes recovery but it didn't accept that either.
Basically I'm out of options now. Everything for jail breaking won't work and I'm not even sure that would activate it.
Does anyone know if I bought an AT&T SIM to activate it, would I be able to put in my TMobile SIM and use it unlocked?
I don't really know what I'm doing..I've never jailbroken or unlocked a phone before at all so I would really appreciate specific links and a plan of action. Has anyone succeeded in activating and using an iPhone 4 without a SIM card?
