Hi, quick question about the tutorial link for the custom IPSW (for unlocking). That link says the jailbreak without BB upgrade would be tethered, but this tutorial says the unlock will be untethered. I'm about to buy a 4 on ios 4.0 and bb 1.59 and i'm trying to figure out how much i should upgrade the software\firmware to. thanks!
