puggy: Update seemed to have gone really quick, just missing sevice provider settings like APN settings, Tethering and voice mail. Have set the APN and Vociemail back up manually but still not tethering. Have restored twice, have tried just loading the ipcc files via iTunes, eg: run the code in Termial, then load iTunes and hold alt and click restore, tried unlockit, rebooting, probably the 101 so called solutions on the net, but still no tethering. It does something but no tethering. Wouldn't mind so much but sold my Vodem stick just last month so this is really, really annoying, need to buy a vodem stick yet again.
Can't wait for the new phone to arrive in NZ will just buy that and hope that fixes it.
Out of the 6 phones around the office 3 are the same problem and 3 work fine, really random anyone else lose Tethering etc?
I had the same issue, seems something in my backup is stuffed. If I do a clean restore everything works fine.
