Hi there....Since I got the 1st iPhone (2007) I never had another locked one...all of them were factory unlocked...

But, I got a great deal on a AT&T 4S, used just for one month and I saw before buying that Absinthe would make my dreams come true....

I'm actually a TMobile client, and I wish to stay with TM, so I need to unlock my SIM CARD......

The problem is the iPhone 5.0.1 is not activated yet...So, I understand that I'll be able to do that with a AT&T sim question is...

1) Is there any way to activate the 4S without AT&T sim card? Or I'll need to buy a pre-paid one?
2) Absinthe seems to jailbreak the iPhone, but does it unlock sim card?
3) Is there any way to unlock the sim card? I'm kind of frustrated right now...and almost giving back the iPhone to get my money back :confused:

you can activate during the jailbreak process and to unlock the 4s you can use the Gevey UltraS Sim interposer. Currently works with 5.01

At the iPhone hacks section.
You don't unlock the sim card. You need to get the iPhone 4S unlocked.
Currently there is no unlock available. There's been talks that gevey will sell a turbo sim adapter to unlock the 4S on 5.0 and 5.0.1
Do not update to 5.1 cause the new unlock won't work.
