Upgrading 1.0.2 to latest firmware with corrupted installer
Hey, I'm hoping someone can make a recommendation... My first generation 8GB iPhone is running under 1.0.2 version firmware. It is an unlocked iPhone currently operating on TMobile. My friend used ANYSim to unlock the phone about a year ago.
My Installer application is corrupted, it will no longer open. I am wanting to update the phone to the latest firmware. If I go into iTunes, click on restore, do the latest Apple upgrade to version 2.1 firmware, then open QuickPWN and do the installation with the 2.1 firmware and BL-39 and BL-46 files, will I encounter any problems? I wasn't sure if I could upgrade my phone in iTunes to 2.1 since I have already unlocked/jailbroken my phone. Do I need to virginize it first, or just go ahead with the plan I've outlined above? If you think I need to virginize, then how do I do this since I can no longer open my Installer application and download the virginize program?
Thanks so much for any feedback -- I really appreciate it!!
