I followed the iClarified jailbreak instructions to a tee. They worked perfectly on my iPhone 3GS, but did not work on my wife's so far (keeps locking up). They both say 3.1.3 (7E18), but I do see that my modem firmware is 05.11.07 and hers is 05.12.01. Is that the reason and if so, is there ANY way around this so she can have hers JB as well? Thanks!
