My 3GS is on iOS 5.0.1; BB 6.15.0;
New BR ;Unlocked with Ultrasnow.
Since I don't have the original carrier SIM , would it be possible for me to create a custom firmware ( 6.1) with Redsnow and restore through iTunes and JB with Evasi0n ?
Would the original SIM be required during JB ?
Would Ultrasnow unlock work subsequently?
Thanks in advance.
