Novice Question 3G Jailbrake & Unlock
I have two iPhone 3G’s, one has IOS 4.01 (modem firmware 5.13.04) while the other has 3.1.3 (modem firmware 5.12.01). Both have already been jailbroken using JailbreakMe.com and then unlocked using ultrasn0w. I would like to update both to IOS 4.1 but want to make sure that I can also unlock them. Can I do that using the latest version of PwnageTool, should I install IOS 4.1 (thus removing the jailbrake) and then use PwnageTool to jailbrake the phone? After jailbraking with PwnageTool do I run ultrasn0w or should I use some other app to unlock both phones?
