Hi, So got iOS4 on my ipod touch 2g which was previously jailbroken. When i jailbroke it using RedSn0w cydia appeared, as did multitasking. However when i tried to use aptbackup, it put my ipod into safe mode, and restarting and rebooting didnt work. so i restored, and am currently un-jailbroken. Should i try again? I don't know what went wrong.
