I'm using ipad 2 wifi+gsm. In IOS 5.1.1, it was totally normal, but when i upgrade to ios 6, then i lost my 3G connection. i only get the EDGE. I've tried a clean iOS restore for my ipad, and set as new ipad rather than restoring my old data first. And the 3G connection appear. But when i restore the data to get my old settings, then it back to EDGE. Would you give me any suggest to get back my old data and the 3G connection, please. Thank you.
