I am using a iPhone 2G and used Pwnage tool first time for the update to 3.0. Used different solutions before and activated with ziPhone a long time ago. Since then I could simply take a new FW and it stayed unlocked and activated, just had to jailbreak again.
Tried to update to 3.0.1 today and it stayed unlocked but the activation was gone. If I use Pwnage can I not simply update to a new version and it stays activated?
