Apple Thoughts: Monitor Your iPhone Data Usage

"It's no secret that iPhone users are data whores. Whether it's the access they have to data-connect applications, the ability they possess to stream video and audio, or how they utilize the Web browsing experience in general, iPhone owners as a group use more data than the average smartphone user."

I suppose if you need to keep close tabs on your usage because of your plan, or if you just want to get a screen shot and email it to de la Vega to show him that you aren't a data hog like he says you are, then you might want to get this $2.99 USD application. This also monitors your home broadband usage for a limited number of carriers, they list them on their website. It isn't too useful for me now but in version 1.2 they will be adding AT&T to the mix so perhaps.
