itunes problem

hi all,

I upgraded my phone to 2.0.2 firmware and everything was fine...but when I tried to install pc suite and connected it asked me to install some netdreagan file and restart my phone and when I dint it I was not able to connect it back to itunes. When I connect it says itunes does not support iphonw ^.1" msg is displayed and asking me to restore.

I have jailbroken and restored using winpwn latest software. Is it ok only I restore my custom firmware using itunes or do I need to again do the entire pwnage work from the beginning.
