Im planning on using the Iphone for wifi only and want to activate using winpwn. so want im wondering is when it asks if you wanna use it for at&t and if you say no it activates it, will i still be able to use the sim card from my phone right (with at&t) now without having to buy the extra data plan?

you should use quickpwn it can activate 2.2.1 where as winpwn did not make a version even for 2.0.1...

QuickPwn says can activate only version "2.0." and even don't detect my iPhone?

All OK

i thought iw as the only one to see that error message but a newer quickpwn 2.2.5-2 was released and that version works fine

My mistake. I was still on 1.1.4 and I was expecting QuickPwn 225-2 to detect my iPhone but it didn't. Actually it did because it says it can only unlock 2.0. version and this means it already detected and it knows my iphone is 1.1.4 and gives this message. Anyway after updating to 2.2 it did detect without any problem. Just wanted others to know in case if they have same problem as me.
