Its been two months with my new service from Sprint. Got the Samsung Epic 4G. Well, I've been downloading 720p/1080p music video from you tube. Like all day long over 24 hours. Well today its very evident that SPRINT has killed my data connection period. 4G doesn't even connect and 3G doesn't work. I was able to connect to 4G once and download a music video. Immediatly after the download finish, 4G disconnected for good. Its like Sprint has a daily or monthly limit? I pay for unlimited data and that WTF I want ! I forgot to mention. When I go to update firmware or prl. 4G lights up,connects with full bars. Checks for updates says firmware is up to date. The it kills 4G and it disconnects! This makes it obvious what SPRINT is doing.
