pocket pc/cell phone

Wasn't really sure where to put this, because, well, it's about a cell phone. More particularly, communication to and from it.

I know this is a forum dedicated for the most part to PCs, but really cell phones are computers and becoming more and more like mini-pcs every day.

Anyway, on to the question.

You know how when a phone is about to ring or get a text message or something, and it's near speakers, you can hear it in the speakers? Well, I'm sitting here with me new phone, and though I keep hearing that (not really loud, but can still hear it), I'm not getting a text message or phone call, so what is being transmitted? It may be a little paranoid, but I'd just kind of like to know. I'm not really sure what all types of traffic is used for a cellular connection, but it just seems like unless I was actually using the connection for a call or data transmission there wouldn't really be that much traffic. Any ideas?

Not sure if it's relavent or not, but I don't use a "data" service, just voice and text (which I know is still technically "data", but I'm just saying, as the service provider would say, I don't use a data service).

 

cell phones and wireless speakers are on the same frequency i know, and wired speakers could be

 

Nothing is being transmitted per se. I get it all the time at work when I have the radio on - drives my co-worker in the next office nuts. Basically when the signal strength fluctuates it still triggers a frequency change that affects the speakers.
