Follow me...

I'm off to Seville this afternoon. And I've just downloaded version 2 of google maps. Would be a great asset in a city I don't know (apart from razzing round it on scooters on a launch years ago...). Trouble is, it's a data heavy application and while I have a flat-rate data tariff (with 3) that only applies when I stay within the confines of the UK.
So the moment I hit a foreign city - the moment mobile guidance services acquire their greatest value - I'm disinclined to use them.
Must be a model brewing here for google maps? Ad-supported perhaps - free at the point of use where-ever you are?
The new version (only available through 3 in the UK, they claim... someone tell me this ain't so!) geo-locates you via the 'my location' function. Very useful. I'll find out just how useful when it starts working. First couple of attempts resulted in the 'your current location is temporarily unavailable ' message. Funny, since I appear to be here...

Anyway on a similar 'how much for that data!?!' theme, expect me to be updating twitter (which'll bounce through to facebook status, too) via sms text while I'm away - and not via the facebook mobile app.
So if you want to be first with the news of which paella I'm trying next, follow me on twitter.
(see left hand column further down the page).

UPDATED: My twitter-updates-facebook-updates-twitter ruse turned into a nasty spiralling mess. I will therefore only be updating twitter for the next few days. Like I say... follow me!
