Does your phone work now? If not none of them are going to make the phone part work--and most all directions I have read are clear about this.

You will need to either wait for the 1.1.1 unlocker (supposedly nearly here) or the baseband downgrader.

No it does not work. I have the screen that says Incorrect Sim. Is there anyway to reset the IMEI number back to the original?
