Hey guys, I just got an iTouch today. It has OS 4.1 -MC540C. I know there is a new OS 4.2 out. Should I download that and jailbreak that? or just stay with my OS 4.1 and jailbreak that? I'm just confused with the OS 4.2, some people are saying you can not shut your itouch off or it won't work? Something like that? I'm not exactly sure. Are there any advantages of upgrading to 4.2? Thanks in advance!
