Hi I have bought a new, but unlocked T mobile G1 from the US. It works fine here in Denmark. However, it seems that the guy who unlocked it also sign in to a google account - thus blocking use of Market. Here comes the question. Can I hard reset the G1 ( so I can sign in a new google account) or would that mean the the G1 would have to be unlocked once more? I would like to know that before I try... best regards and thanks for a great forum.
