My DEV Team update failed too and i had to restore 1.1.2
I then restored to 1.1.1
upgraded to 1.1.2
but i can't jailbreak 1.1.2! it keeps crashing on "Reading Flash"
i've done this whole process about 5 or 6 times now and it still wont work...
i dont have the original sim that came with the phone... would this affect jailbreaking?
