So long story short my mom now has 2 Blackberry curves. One of them she uses, one just lies around. She is on the AT&T network and I am on the Sprint network.

I know that one is GSM and one is CDMA and it probably wont work out but im wondering if there was any way that I could get my mom's AT&T Curve to work on my Sprint network? My contract still has a year and I dont want to fork over the cash to get out of it. Thanks to any of you smart people that can help me out.

Short answer......no.

GSM and CDMA are not compatible. GSM runs on SIM cards, and CDMA uses ESN numbers. You would need a SIM card to get that Curve working, and as you know, Sprint does not use SIM cards.

Totally different technologies. Plus, Sprint does not allow a non-Sprint phone on their network.
