Description

Verizon Samsung SCS-2U01 is a very famous target for many hackers,while as Harald said in 32C3,none of them even thought about running a local network upon it.Verizon is phasing out its CDMA network,it's time to play with these valuable blackbox

It looks like the IS95 core network is a bit simpler than 3GPP network,however,there is no project about IS95 at all,Neither the data PDSN nor the IS95 MSC.

I have managed to find some completely out-of-factory ones and try to get some dump of it
