Unlikely that it can be currently unlocked if it is on IOS 5. It will all depend on what the modem firmware is at? Check into that and let me know what firmware it is then I can let you know if it can be unlocked or not. My Iphone 4 is on IOS 5 but my modem firmware is 01.59.00 but I have been very careful to make sure when I upgrade and jailbreak my phone to ensure that the firmware didn't get updated.
