First of all, you should have clicked CANCEL there. You shouldn't have upgraded an unlocked phone. You just locked it. I guess it's version 1.1.2 now, right ?

Jailbreak 1.1.2 is released.

You need to be patience. To unlock your phone, you need to have a WIFI connection. It cannot be unlock if you dont have WIFI. Go outside, malls or any coffee shop that may have WIFI connection.

Try this:

h**p://iphone.unlock.no

Thank You Friends For Helping Me...........
