I put the iphone in DFU mode and open I tunes it detects my iphone and wants to upgrade it to iOS 4.2 is this the correct way to restore my iphone ???please help me !!
what to do??

thanks a lot !

After using the IPad 6.15 baseband, you can not restore with the official stock firmware. You can only restore with a custom firmware file. That's one of the WARNING of using the iPad baseband. Google for instructions on how to restore.
