HELP! Flashing CDMA iphone 4 to pageplus

[Aslan Davis]

I recently got a Iphone 4 Model # MD146LL/A which is CDMA I think (no sim). it was on the C-Spire Network.. I was told by both the previous owner and C-Spire (when I called) that it could be "flashed" to another network .. I'd like to go with pageplus (since the are the cheapest CDMA carrier I can find that has a data package) if possible but how do I go about doing this?

oh also! I'm currently running ios 7 Beta, since 6.1.3 was installed. I can downgrade to 6.1.3 if needed to do the tethered jailbreak. =P
