iPhone 4s 5.1.1 2.0.12 baseband Activation without original SIM?

[acenase]

I updated my iPhone 4S to 5.1.1, and jailbroke with Absinthe. But when I insert the Gevey Ultra S SIM to unlock it, it says "No Service" and takes me to the grey screen saying "Activation Required" and I can't get to the home screen unless I take the SIM out. How do I hacktivate the iPhone 4S? I thought that it was activated when I used Absinthe but apparently not. I'm just trying to unlock my iPhone 4S but I am stuck because it's saying I need to activate it with the original SIM but I am on T-Mobile and I don't have another SIM card. What should I do?

Iphone 4s can only be activated by Original sim , go get an unused sim either from the official carrier or from Ebay. This will save you lots of trouble in case you need a restore, you definitely need it.
