Since 1/1/13 it seems that every time I try to download something from the internet browser to my phone (like a PDF file, or an APK) it fails. The download appears to start (I see the little flashing icon in the upper left corner) and then after 5 or 6 seconds it stops and when you look at the notifications pulldown it says Download Unsuccessful. Wondering if there is some setting that is limiting my ability to download anything OTA? Appears the last successful download was back on 12/26. I don't see any sort of "data limiter" or anything in the settings that might be designed to protect oneself from chewing through data. I AM able to download an app from Google Play Store, just did it. It seems that somehow the stock browser isn't able to download files successfully? I looked there and there also don't appear to be any bandwidth limiters or anything. Help?
