I have been researching on jailbreaking and unlocking an Iphone 4, as I have a jailbroken Iphone 3G and upgraded, and I have realized a couple things confuse me. 1) Is there an untethered jailbreak for Iphone 4 on 5.0.1 that can be used and still unlock the Iphone. 2) If I cut my sim card ,which is T mobile, to fit in there, I can unlock it yes? I plan to jailbreak using Redsn0w, and unlock using Ultrasn0w. Is this possible?

So then would I have to have a tethered jailbreak and unlock it? Or is that not even possible.
