recently changed from iphone to said phone. My average usage was 90mb a month and now it's shot up so that ive used 80mb in 2 days already. I have wifi at home and at work so it's only the periods of time between that it'll be using 3g. Anyone else had this problem or able to help? I have auto synch turned off for emails so I cant think of what else is eating it up? Could be something like the background? I have the one that is a beach and it changes with the weather etc...
