Ok i tried the soft upgrade to 1.1.3 from unlocked 1.1.2 , it failed and gave me the connect to itunes screen.

I downgraded the phone back to 1.1.1 and used the baseband downgrader. I then jailbroke and ran anysim.

All seemed to be good however although my sim card is accepted it will not connect to my network or search for other networks ( i get an error message)

Have i missed something ? Do i need to run the virginiser (i thought that was only for 1.02 )

Please Help me

Stranger still , i flashed 1.1.1 in again and all came up fine , connected to itunes and restored and the signal has gone again.

You need to run virginizer. then restore again in 1.1.
I'm using Jailbreak from Nate true to upgrade 1.1 to 1.3
It works, takes about 20 minutes for upgrade.

Cheers, i have got it working. It appears that Itunes 7.6 does something funny if it sees an unknown sim card
