help jailbreaking and unlocking iphone 3G
Hi guys. I'm a long time forum member here but its been a while since I unlocked a phone. It looks a little more involved and I want to make sure I do it right. I am traveling last minute overseas and really want to unlock my phone but I just dont have time to research it all. Can you guys help? Here's my current setup:
-iphone 3G, was jailbroken in the past, but not now
-Version 4.2.1 (8C148)
Do I need to jailbreak BEFORE unlocking? Please advise the best method(s) for this. Aslo, i would prefer to have an unteathered method. Thanks for your help. I usually have time to look into this but am really pressed at the moment. I trust you geniuses to point me in the right direction. Thanks!!!
