I dont know what happened but I turned off wifi last night to do a speedtest on 3g with my ipad 2 which has ios 5 beta 1. I used it all day at work today fine. around 1pm I closed the smart cover and put it in my incase bag. Around 10pm I get an email saying im nearing my data allowance. At first glance I thought it was my girlfriends iPhone because she usually comes close and my phone bill ends in a week. upon further inspection its my ipad data plan! it renewed THIS PAST WEEKEND. I usually use about 300mb a month on the ipad out of 2gb and somehow ive already used 1.8gb! I opened the ipad and had a TON of warning pop ups but they kept popping up so fast I couldnt even read them. Something about wifi and 10000 or something. I had to turn it off to get them to stop. I think it might have something to do with auto downloads. So just a warning keep an eye on ios 5! EDIT: I checked automatic downloads I had Music Apps and Books set to auto download however I had CELLULAR switched to OFF. Not to mention I havent downloaded anything new on any other device that would make the ipad download anything. unless a bunch of apps all of a sudden updated today.
