I've had the IOS 6 beta since Beta 1, and have noticed my apps using much more data than normal. I've went over my 5gb data plan (ATT) for the past 2 months (last month I used 10gb!!). I've done expirements with a IOS 5.1.1 iphone and my phone running the same apps and checking their usage, mine has increased by 50-75%! (I cleared both iphones of running apps and then only opened apps one at a time). Has anyone else encountered this problem, I've noticed it on my Iphone 4s and Ipad 3+4g.
