Root Eris on sprint?

[da man]

Is there any chance of activating the Eris on Sprint? A job change has forced me into using Sprint and the Blackberry they provided. I hate it and want to use my Eris that is unactivated now. Any ideas? Flashing a new radio?

The radios on the Eris and Hero are the same. Erises can be flashed to Cricket and also MetroPCS, but I'm not sure about Sprint. I've heard they won't activate a phone they didn't sell.
