"Revol can now flash non-Revol phones over to their network using Houdinisoft reprovisioning software (most CDMA phones will work Sprint, Verizon, and Alltel), however there is a $30.00 charge to do so." - wikipedia
AKA Call Revol and see what they say. I know I saw something around here at one time or another that their "houdinisoft" was unable to flash the phone a while back, but now that it's been out a while it shouldn't be a problem.
Revol is actually an Ohio company based out of the city of Independence. Their towers partially were "Cricket" brand, but they bought some of them. Nice service if you're going to be in that calling area all the time, or if the $5/mon fee is OK in your eyes. Also good to have a month-month carrier for your cell sometimes.
