Hi, I'm having this problem. Erratically when I'm using an iphone sized app, it will go from 2x back to 1x. I wish to have it stay at 2x all the time for all iphone apps. Is there any way to do this? Im on 5.1.1 jb ipad3. The funny thing is that this didn't happen to my other ipad3 which i have since sold.
