Re: scanners - the radio sort
You can listen to loads of stuff.
taxis, airplanes, personal radios etc.
Have a search around for scanner frequency listsing that show the bands & what they are allocated to.
Forget about listening to the police etc.
They all changed to encrypted radios a while ago.
as for the law, its an ass, you are not supposed to listen to anything that your not permitted to (like the police). But it never usually stops anyone.

Mobile use very high frequency waves - practically microwaves, if a scanner could get to that high a frequency - I think they are encrypted anyway.
Most phones these days are digital meaning you would need a kind of modem to listen in.

Re: scanners - the radio sort
I used to have a scanner that scanned from 25mhz to 1300mhz. Mobile phones were about 800mhz (anologue) Digital ones are on a complete different wave length.

Re: scanners - the radio sort
I believe Digital phones are on 900Mhz (BT, Vodaphone) or 1800Mhz (Orange, One to One) - but as the signals are digitally encoded you can't listen to them.

On analogue - totally insecure.
On digital - very secure - you need some serious stuff to tap into and decode it.

If your talking about matters of national security then don't forget yours or your friend phone could be tapped or your house could be bugged but if your just talking about what to get your mum for Christmas I don't think you have too much to worry about

Re: scanners - the radio sort
I've got a scanner, also several trancievers that have "wideband recieve" on them. I mostly use them to listen to Amateur Radio(which my transcievers are designed for anyway), and the airband.
When I go the airshows i would say 4 out of every 5 people has a scanner on them, and the military/civilian police never say a word.
However, this is the exception to the rule, the law states as Zoombini said that "it is a offence to recieve anything not intended for general reception", so basically you are legally allowed to listen to Amateur Radio, CB, and Broadcast Radio.
On the security side of things, if a radio user want their transmissions to be secure nowadays they use some kind of digital encryption or frequency hoping, this makes it very hard if not impossible for the conversation to be over heard. Systems that use encryption include digital mobile phones andsome fire fire brigades, ambulance and police forces(TETRA).
