Hi - I just purchased a ( locked ) ipod. I haven't used it yet, as I don't want to screw up anything if I want to unlock it. My questions are: Do I have to unlock ( jailbreak) it in order to: Have a POP3 email application? Utilitze Yahoo IM applications? Use GPS Functions/ mapping functions from a hotspot? I really don't want to risk unlocking and having the OS problems that seem to be evident for many windows users. OS is 1.1.2. Any help is appreciated!
