Is it possible to activate my NS4G on another carrier or something?
Yeah, I think lots of bad esn Sprint phones are commonly flashed to Boost or Cricket wireless cuz they dont check. Just be careful before you pay someone to flash it, because u want to make sure u get voice mms AND data - not just 2
Mainly, I think you would be flashing the radio firmware to Boost or Cricket. If you are interested in doing this, one website that has lots of info on this is <a href= "www.howardforums.com"> Howard Forums </a>
