I just recently upgrade from a Sprint 7250 to the Sprint 8830 and absolutely love it. No issues with the device what so ever. While I know how terrible their CS is, i usually only have to call them 2-3 times every 24 months... usually regarding upgrading my phone at the end of my 2 yr contract. With this being said, you know what to expect if you call their CS, but i havent had a need to much. I love their coverage, love their devices. I'm good.
