I am trying to unlock my iphone 1.1.2 though a software I bought from ebay. i'm stuck
and i have tried everything. i'm on the part where i'm suppose to download an application called appSnapp and everytime i do this nothing happens
. for that matter, is it really necessary to downgrade my 1.1.2 to 1.1.1 through iTunes. it came out of the box as 1.1.2 and it hasn't been tampered before. many thanks.
