    First piece of advice is to never ever use Ziphone. It's been known to really screw up some iPhones. First mistake right there. Was there any reason you decided to downgrade the firmware?

    i downgraded because i heard thats the only way you can unlock the iphone from a pc and do you think that ziphone screwed up my phone?

    I can't say for sure. I'm not sure by upgrading to 2.0 if that changes the in the radio. I myself have not downgraded from 2.0. Sorry I can't be of much help here. Maybe someone else can chime in for you.
