Help for 3G
I would like to thank you all for your help in advance
I am not very technical with iphone's so please bare with me!
I have iPhone 3G iso running 3.1.3 and baseband is 06.15. But it's some how not unlocked and I don't have cydia installed either bought it like that thinking it would be unlocked already but it's not. Can any one please give me instructions how to unlock and jailbreak my iPhone 3g???
Not sure what previous owner used to load 6.15 base band does it matter
if I use any different software ?
Thanks once again all
The previous owner updated the iPhone to IOS 4.2.1 or 4.1, then to enable unlock again, they installed the 6.15 baseband (which can't be removed or downgraded).

This baseband can be unlocked by the recent versions of ultrasn0w.
So.. jailbreak with redsn0w 0.9.2 or 0.9.4 (when redsn0w asks for an IPSW, give it a 3G 3.1.2 IPSW - downloaded from here http://www.hackint0sh.org/f127/22056.htm )
Then load Cydia and install ultrasn0w.
Guides for both procedures can be found on iClarified.
