By "Operating System", I meant the software that runs on the device, scheduling and managing applications. Like, the "Operating System" on my computer is "Windows XP". CDMA VZW sounds like the network protocol name. Or, is that actually the name of an OS?
You mean like Windows Mobile or Palm OS 5 for mobile devices? I doubt it has a Operating System like that, this model is not a Smartphone. Unless your talking about a regular cell phone Operating System if so then I have no idea about that.
