My wife and I each have HTC Heroes... the Sprint versions. We are approaching our upgrade availability, and will be doing just that. So... we have two perfectly good android Hero's, two kids who like to play games and listen to music... and are wondering... Can we still use the Hero once the Sprint service is disconnected? Can it be used for: 1) MP3s? 2) As cameras? 3) Can we still access the app market via our home network? Also... if anybody has any how-to's to help us with this, it would be great. Is there anything I need to do with the phone (upgrade OS or anything) BEFORE we switch phones? Thank you in advance for help and ideas!
