I decided to jailbreak my iphone today so I used Quickpwn and it all went fine. Then I realised I had no signal anymore (I'm on an 18 month contract with O2) and not even the O2-UK thing in the corner. I've just managed to get back to my original settings by restoring to 2.2 (Shift click and restore) followed by an update to 2.2.1 but I'd like to know if there's a fix for this. All I did was normally apply the QuickPWN which went fine and Cydia appeared on my springboard as usual, just no signal or even display of the O2-UK

I had a similar issue in the past and i found out i forgot to tick the unlock thingy . . .

Everything worked afterward.

Yea, i read you are in contract with O2-UK, but maybe there is issues with the jailbreak ?

Maybe just unlock to be sure, unlock will work for sure . . .

he has a contract so maybe the mistake was having unlock ticked.. if you have a contract you dont use the unlock option just jailbreak.. cydia installer and bootlogos or the ones you want.. i dont use installer and i dont bother with boot logos the ones quickpwn changes them to are no good
