Ok a bit ago I posted a thread about editing mms apn with iphone configure utility or whatever...lol went ahead and jailbroke the phone, installed tetherme, and got my mms settings set. Now my question is - if I want to return to stock/unJB iphone, can I do this while still keeping the mms apn settings? Like can I remove the jailbreak while still keeping the mms settings I set with tetherme?
