I agree, it sucked way more when they first launched it nothing worked for me. But now you just have to look harder, to get your data info, log into my sprint.com and then when you get to the Main page, click on see all usage for your phone, scroll down to Data/others and click the See more + button on the right, or log in and click here
http://mysprint.sprint.com/mysprint/...ageDetails.jsp then scroll down to data/others click See More+
and if you want to see data usage for past months (not current unbilled) try here
