I did a search and can not find ,were on my bold the data usage number is .I spent about 20mins last evening going through the apps looking for a counter.
also I did some browsing loading some web pages using the icon on the main screen ,found that the bold is fast .now the test to try what it with java script enabled . the reason for the question ,I have 6g but when siting with a latte in chapters one could spend way to much data and get a heart attack of a bill for going over 6g.

The BlackBerry Bold has no data counter. You could try your luck mit myBoxTone: myBoxTone - Empowering mobile users to manage their own experience
