Hi chaps...

I have just upgraded my iphone 3g 16gb to 3.1 (using [ame=http://www.youtube.com/watch?v=cyo9oXC35dA]YouTube - Jailbreak and Unlock iPhone 2G/3G and iPod Touch 1G 3.1 Firmware on Mac and Windows[/ame] )

And after upgrading & unlocking via cydia & installing repo666.ultrasn0w.com via sources) my phone is now searching for a signal.

I have looked at several cases of this that tell you to reset network settings & stuff, but none of them work.

Can someone please help me out on this???

Thanks in advance
