Pretty much anytime i have my streak on wifi at home. And when I leave with my tab in had, I sometimes dont get any network connection, no E, 3G or 4G, if GPRS is possible, i am not getting that either! Anyone else having this problem? And sure the quick fix is rebooting the device, but the fact that it happens is rather odd. And I'm in a well covered T-Mobile city, San Antonio, Texas!
