im now running ios6 on my iphone 4s i do have a gevey ultra s and its bypassed the activation for the sim card im using but it just says searching at first it did say orange - tmobile so it may work or just glitched out , but to all you who are trying to update to ios and you have it jailbroken on ios 5.1.1 its best off if you factory restore it cause you will encounter loads of errors as i did and had to restore and update through itunes
