As far as I know the 3721 that like you used once?
I have bought my 450 in fortress at the early this week, hopping to be jailbreaked . the firmware of this brandnew machine was still 2.09. I needed to downgrade the machine by the use of downgrade-450 sp-2014-01-17 file, before I jailbreak the machine with cfw 4.04 by activation code. Once I jailbreak it, then I could upgrade it to cfw 5.05 directly without the need to enter the activation code again.
is that strange? no need to use the code machine again in update cfw 5.05 !
