Do yourself a favor.... – DataMan - Data Usage Widget Review

GET THIS APP. Just moved cross country, and used maps/music/etc A LOT. I've never had an issue staying under my data cap, but in 3 days I had used 80% of my data for the month! This app not only told me how many days I had to stretch that 20% over, but it has a widget for Notification Center that tells you, without opening the app, where you are in your usage. Also breaks down wi-fi use vs cellular, which is nice to know. Can't recommend enough, A++!
