Sorry for threadjacking, but to the OP, is 4.3.3 with 4.10.01 on i4 still an untethered Jailbreak?
I don't need the carrier unlock since I'm on official AT&T but I do want to upgrade my baseband because anytime I've upgraded to 4.3.3 and kept 1.59 BB, I was unable to get signal and had MMS issues and had to downgrade to 4.2.1
