How often does the Data usage message update? I sent in a query for one last night and I got 31mb used, today I get a message telling me I am 65% over my limit an have used 160 MB. All I used the internet for was chat and some web-browsing (like 5 pictures and a few webpages), but nowhere near 120MB. During the time frame between when I checked I was on an airplane for 4 hours (so no 3G) and then went to bed and got the warning when I woke up. So how often does the data usage message update? Also, how immediately do you get the Data usage warning mesage?
