Many Sprint phones will work with Metro PCS. You need to check with your local retail store to see if they do the Flashing. The Metro stores are the ones who Flash to phones, but I know the NY area doesnt allow this, as they dont even have the BB's, but other Metro areas do. Best thing to do is take it in and see if they can. If they can, its like 30 or 60 bucks and ur good. If they can't, then no one can.

I don't think it can be done, please read this post from pre central if you can't make it work right on verizon Metro ain't going to happen
