I Have just run jailbreaker after upgrading to 2.2
my phone now has no signal ,it was working fine up until then, has anyone any ideas what might have gone wrong
Iam on O2 in the UK
i have looked at the phone setting and cant see anything has changed
i use this phone for work but receiving or able to make calls
Do a restore of 2.2. Then rejailbreak making sure activate is selected. Or you can look for boot neuter in cydia if you have wi-fi available. good luck.
