just got: iPhone 3GS, OS 3.1.3(5.11.07)/old bootrom
I just bought a used iPhone 3GS with old bootrom.
I was told the iPhone was jailbroken with blackra1n(RC1) and unlocked with Pwnage tool.
I havent connected the phone to my Mac yet, because I am afraid of iTunes updating and bricking the phone.
1. Can I connect the phone to my Mac without the danger of bricking it?
2. Should I make a Backup of something? If yes, what & how?
3. Can I update my unlock/jailbreak? (I have an old blackra1n version with wifi problems)
4. Or should I rather make a fresh install? ( Reset everything to Factory settings and using the latest blackra1n/blacksnow to unlock/jailbreak)
