I have an iPad 2 3G + Wifi (GSM). For the past few weeks my iPad's 3G hasn't been working so I've been left using 2G which isn't very useful at all. I contacted my provider and they assured that they aren't having any problems on their side. I even swapped my data sim card with another iPad and it worked on their iPad and I was still stuck on 2G - so from that I determined it was my iPad. I then restored my iPad back to 5.1.1 and the 3G network was fine again but on low signal despite me being near a 3G tower, then when i restored from a back up it turned back to 2G. I then restored backed to factory settings again however this time the 3G wasn't working again. I thought it might have been the jailbreak but after the restore without even re-jailbreaking it, can only be the actual hardware? What else could I try? I'm thinking of just taking it in to the iStore?
