hi, i m new here. Can you guys help me?
I'm using iphone3G from US with sim unlock. Currently firmware 2.01 with 01.45 baseband. How do i upgrade to 2.2 firmware? I know we are suppose to use itunes to restore to 2.2. and Quickpwn after that.
Will it then relock my US iphone 3G?
Thank you in advance.

No need any custom firmware, just download the 2.2 firmware from here (could take some time as the size is 200mb++) and shift + Restore in iTunes. Use Quickpwn to jailbreak and add the source (refer to 1st page) for yellowsn0w in Cydia. Install the package, reboot, wait for 1 minute at the 'slide to unlock' screen and eject your sim and put back. Thats should do it.
The most important part here is Jailbreak. Don't use any custom firmware downloaded from an untrusted source. Who knows what they put inside that firmware. That yellowsn0w.net site is not from dev team so I might suggest avoiding it.
