I will have atry later at that, what I saw some time ago using a Contact Dongle before PAYT dongles cam out you could run a PC prog that also captures the LAC & Site IDS on you travels and loged it against time and GPS it you had one.
I've used similar program on Linux that would give this information, there might be a 3rd party app but from Vodafone's perspective we don't really offer this information to customers.
As John A has mentioned you can do this by using AT commands, depending on you're IT ability you may be able to script this.
