GREAT question.

The short answer is that for now I believe you're safe on cellular and WiMax
type of networks. I *believe* that the data is encrypted, but even if not
sniffing equipment is not nearly as prevelant as it is with WiFi. Any laptop
can sniff Wifi. I know I happily use my cellular connection without the same
encrypting safeguards that I do when I use WiFi. (Though I keep my firewall up,
since it is a direct internet connection.)

I honestly don't know about internet phones. I know that *some* are encrypted,
but which I do not know. I'd check with the providers.

I presume you're talking about a LAN. But what about the WAN (if I understand the term correctly). I have just subscribed to a wireless ISP - not a WiFi - but the kind where the ISP gave me a wireless modem that connects to the nearby cell tower. Is this kind of connection safe? The person in the next office uses a ISP/wireless modem with an internet phone. Are his conversations secure? When we talk about "out there" (on the internet) versus "in here" (on the LAN), is the trsnsition at my modem or at the cell tower? Or where?

The question of using an internet phone with a wireless modem is a big deal, because it is the means that some phone companies are using to provide local phone service which bypasses the land lines yet acts like a landline service. So if there are any doubts about its security this will be a major concern.
