Just downloaded a radio app from the appstore and it shows you how much data you are streaming while using it. To my amazement it uses about 3meg of data in 1 minute

Will o2 frown on me if I use this app every morning for an hour on the 3g connection.?

No they wont. If you left it running all day, every day you can expect a polite letter asking you to calm it down a bit. But O2 freely admit that they sell the iPhone based on it's abilities to do this sort of thing, so can't and wont then complain when owners make the most of it
