I just upgraded to iOS 4.1 from 4.0.1. I had Mitime working and activated on 4.0.1 before upgrading to 4.1 like it says on the website mitime.info, everything is activated on Mitime currently on 4.1, push is connected, and it says firmware restore would be ok, facetime option is there but when i try it keeps saying call failed, please help!
