You have been slinging over a year when the app was released May 12 of 09?
To be more specific, yes more than a year using my iPhone's 3g data stream tethered to my laptop prior to the iPhone app and using another app on Cydia to make the iPhone think it's using wifi when actually on 3g to sling it to the iPhone. Sorry I wasn't more specific. 🙂 Either way was still pulling the data in via my 3g connection. Good to know it's less now in the actual app.
