Hi, I've just got myself a Desire since last week and I am really really happy with it. It's my first android phone (previously had a Nokia N95) so I am still trying to get my head around it. I've just realised that the phone is using massive quantities of data over the last two or three days. I have installed an app to show me how much and it is saying over 4gb, a lot of it during the night when I have not being using the phone. I have obviously been using the phone a lot since I got it but nothing close to that amount. The most data hungry app that I can think of that I have used is Grooveshark and that was only for about 20 minutes. Also I have gone into all the apps I can think of and made sure that they are either set for manual sync or else no more than once a day. Is there a way for me to tell which app or widget or whatever is using all of this data? I am sure I have forgotten to change the settings on something but I cannot figure out what it could be. Any help would be greatly appreciated.
