EDGE/CDMA provider do not block SIP. I have tried this using an actual SIP phone [also with Cisco-SCCP] and a Wireless CDMA card from Sprint, both connected to a router [Cradlepoint routers supports the Sprint USB USB-WAN type connection] and was using it in my car as part of the office PBX. I've also traveled with such phone to the UK and used a local GPRS wireless card and it worked just fine.
So obviously, as soon we'll break that barrier, and a sip client for Blackberry would become available, it should be working great.
