Dude... 2.5 hours a day of streaming music will push you over the limit... I hope I get to keep my unlimited when I upgrade from a GoPhone account to a post pay account.
I stream Pandora for about 4 hours a day, 4 days a week (64 hours average a month) it shows as 1.8GB alone. I checked my usage and I've never been over 600MB a month.
Kid, I think I know when I'm using 3G or WiFi.Did it occur to you that you might have been on Wifi?
OMG SLIDE STREAMING MUSIC TO 1 HOUR PER DAY AND IT TAKES A GIG OUT OF YOUR MONTH WITH NO OTHER USAGE... What are they playing at!??!??!?!
