cdma security

My understanding is that by it's very nature, a cdma signal, is all but immune from being"snatched out the air" by someone with malicious intent. If this is not so, someone knowledgeable please disabuse me of this notion but that leads to my query. All of the security products I have looked at fir Windows Mobile are for gsm phones and center around encryption and sim card management as far as the firewalls go. Is Windows Mobile vulnerable? I would assume so because it's ,well, Windows. Can anyone recommend a cdma smartphone compatible secutity suite? Any and all answers and assistance are greatly appreciated. I'm at my wits end and tired of talking to IT techs who, because they don't speak good english, can't even understand my questions, let alone my concerns.
