My wife upgraded from an Incredible2 to a DNA last month. We pretty much immediately got a message saying she was hitting data use limits, which we chalked up to her doing a large amount of app and music downloads. This month she got another 3/4 of the way through the billing cycle. So, I looked at the data usage. Usually, she has slacker and pandora way over anything else. Now Android OS is almost double either of those. Something I've never seen. Any ideas?
