In need of expert help from you forum gurus
Hello everyone. I got my hands on a iPhone 3GS unlocked jailbroken on 4.2.1 firmware on T-mobile. The modem firmware (baseband right?) is 06.15.00
My question is what is the latest untethered hacked firmware available now that I could still use to unlock my phone for T-mobile's service? And how would I go about updating my iPhone in a proper manner so I could jailbreak and unlock it again in the correct way? And my last question is what are the new features of the newest firmware that is out?
If anyone could help me answer these questions I would greatly appreciate it! There was a time ago when I had kept up with what I had to do to properly hack everything the right way, but its been a while and instead of just browsing youtube videos and get lucky I thought I post on these forums and see if any of you souls could help me out. Thank! :)
