is this what i need to jailbreak my iphone 3g (3.1.2) without it being tethered?!! please give me the correct answer as i have been told so many different things.
Tethered jailbreak is ONLY for the newer iPhone 3GS produced after week 39. So you will not have any issue such as tethered jailbreak. And yes blackra1n is a great way to jailbreak.
