Just brought a 32Gb 3gs has 88936... and baseband 5.11.07. I tried to find [iboot.....] version but not luck. The Iphone has never been Jailbreak or unlock anything. I've been reading a lot of post and I got lost. Now i need help. What is the best (safe and easy) way to jailbreak and unlock? I was thinking to try Redsn0w 9.2, but i am afraid that i will do something wrong and i can't go back. Thank you.

You have old bootrom/iBoot - that is good news

Use redsn0w to jailbreak, after this ALWAYS use custom IPSW. Stay on the pwnagetrain.

Thank you so much for very quick respond. How do you know that i have old bootroom/iBoot? (Maybe is a dumb question) and can Redsn0w 9.2 unlock my iphone? and what you mean "after this ALWAYS use custom IPSW. Stay on the pwnagetrain"? Could you more have more detail? I used to do 1st gen Iphone easily. However, this 3gs is so confusing.
