It's good that you don't need an unlock, you don't have to worry about the baseband. Seeing as how you don't have SHSHs saved for 4.1 and below, you can only go to 4.2.1 which is fine since you're with the official carrier. The problem is, the jailbreak is tethered at 4.2.1, so it's up to you if you want to deal with that. If not, stay at 4.0.1 until an untethered jb for 4.2.1 is out.
