Help ways to determine which app is using data?

my data use is off the charts and while i use my phone a lot for web browsing, 3 gigs a month seems ridiculous to me. is there a way to determine which apps are using the most data? thanks.

TrafficInfo or similar apps will do this.
Last time I checked, I was using over 2 GB a month though, and I am by no means a heavy data consumer (no social networking or online gaming). All that background syncing and data usage just mounts up, I think. 3 GB may not be unreasonable, hard to say though.

Check out PhoneUsage, it tracks data, texts, calls and it provides some pretty cool graphs. Specifically a graph showing which apps are using the most data.
