I am new to the ios family, with just a month of use/experience with ios. I just wanted to know whether ios GM versions have any expiry date just like the beta versions? Will the Ios 7 GM have any expiry date? I am asking this because i shall/may not have any internet connection till from Sept 15 till december this year. so in case the ios expires, my device could become unusable. P.S.: my device is Ipad 4th Gen. Please, any help would be thankful.
