Ok, I am a noob and hoping someone can help me. Trying to unlock and jailbreak iPhone 3g (firmware 4.2.1, baseband 05.15.04).

Can someone tell me what I need to do? I've already updated to latest firmware via iTunes. Do I use Greenpois0n? Redsn0w? which one? I'm very confused...

Also, once unlocked and jailbroken, does this mean I can no longer do updates via iTunes?

Sorry if this was asked before. I've done search on here but can't find a question that is similar.

Thanks in advance, Naomi

There's no unlock for that baseband. You can jailbreak with greenpois0n or redsn0w on 4.2.1. Don't worry about updates, 4.2.1 is the latest for you, and always will be.

Hi spockers, Thanks for the quick reply! So, there's absolutely no way to unlock my iPhone 3G to use on another phone carrier?

Only if you can get an official unlock from whoever you purchased it from, and that only applies outside the US.

Ok, I've done some more researching and this is what I understand:

1) Because I am on BB 05.15.04, I cannot unlock my iPhone 3G. Is this correct? 2) In order to unlock, I need to upgrade to 06.15. Correct? 3) Upgrading to 06.15 BB may cause problems with GPS. Correct? 4) There is no hack or fix for this possible problem with GPS on 06.15. Correct?

Is there a way to go back to a BB where I CAN unlock my iPhone 3G?

Thank you everyone!

All correct. There is no way to downgrade basebands. If there were, everyone would just go back to 01.59 and be done with it. :P

Hi spockers,

Ok, thank you. I'll just wait for a hack to unlock for this BB.

Thank you!
