so i learned my lesson, just got the bill. EDGE was horribly slow and i used it maybe 2 days in Mexico. I was charged under DATA ROAM usage and my bill is now $350. In some cases, i was charged $42.00 for about 2,100kB. I cant believe it was so much and soooo horribly slow. Oh well, lesson learned, i'll be more carefl from now on
