How does an iPod Touch or iPhone know where i am?

We have been getting lots of calls recently from people wanting help setting up mail on their iphone or ipod touch or syncing their iphone to their car bluetooth, so we decided it was about time we got in on the action and saw what all the fuss was about.... So, we're now have a shiny new iPod touch in the office (we use Orange for our phones, so can't get an iPhone just yet). Anyway, after upgrading the software to version 1.1.4 through iTunes and upgrading to the January software release we started playing around with the applications. For those of you who use the web alot you'll probably have come across Google Maps (http://maps.google.co.uk) which is pretty amazing. The latest release of the Touch and iPhone have a version installed. Right at the bottom there is a button which when you press it, assuming you're connected to wireless, it zooms the map in to where you are. Now, i could understand how this works if you're connected with an iPhone due to triangulation with phone masts etc, but as i'm connected through my office wireless, how does it know where i am? As with all problems that can't be answered straight away, I googled and found a useful explanation on someone elses blog. The link is below, so if you have an iPhone or iPod Touch and you have wondered how it knows where you are, then take a look!

Also, if you have one of these gadgets and you're trying to work out how to get your email from Exchange at the office onto your device, just give us a call and we'll tell you all about IMAP.
