on the one X there is a data monitor.
if you install a different RUU (asia custom for example) obviously all the att custom is gone.
would it still be able to monitor your data so precisely? I've always used about 1.5 - 2.5 gb a month on 3g/4g
but in one day in the city where they have lte I used 5gb and I had to airplane mode and then un airplane mode to download things.
I ended up getting a phone call from att when I got to 10gb by the end of the second day.
