also, when i was doing this would i have to factory restore my phone before going through all of this?

thanks

What iPhone do you have? As in 4, 4S, 3GS?

And have you considered just using the Redsn0w tethered jailbreak?

Like what Brandan said, it really depends on the iPhone as, and you have 2 choices using the redsn0w tethered, or you can just wait for a untethered jb to come out.

And no just sync. unless you stuff up the jb'ing process.
