so i just got my step mom's old iphone 4s as she got the 5, and noticed it was on 5.1 and coudln't find a jailbreak for it. can i jailbreak this device or am i stuck with no jailbreak? =/ she didn't jailbreak before so there're no old shsh blobs and it wont show up in tinyumbrella, my ipod touch 4g doesn't show up in tinyumbrella either... any idea why? the itouch is jailbroken
