I was on 1.0.2, and had it unlocked for TMobile. It worked fine.

I followed instructions to upgrade to 1.1.3 and then downgrade to 1.1.1 but I never got past the first step. When I tried to upgrade through ITunes the upgrader gave me error 1016 and did not complete.

After a restart the phone asks to be connected to ITunes which in turn asks to upgrade to 1.1.3 and I'll end up with the same error.

I downloaded 1.1.1 and tried to restore to that firmware but had no luck. I wasn't quite sure which file to select in in the 1,1_1 folder though.

Can anyone help? Thanks.
