You'd be best to sell your Eris and find a good deal on a Hero.

Hero actually also only has 65k color screen, and Eris has 262k or so.

The proximity sensor is a joke. It's a light sensor, next to the earpiece. Not a true proximity sensor.

And the capacitive buttons are awful. I WISH I could put a Hero on Verizon, because I'd kill for physical buttons. The capacitive ones, you're not sure if you hit them, especially if there's lag, and they're harder to accurately hit.

Outside that, Sprint, nor Verizon are both companies that will almost NEVER allow a non-Sprint or non-Verizon phone to be on them. The Eris would be VERY hard pressed to be on sprint. You'd have to make the MEID look like a Sprint phone's. Good luck with that.
