I was quietly sat in a London restaurant when my phone bleeped into action. Would I like to receive a Bluetooth message from "Coca-Cola".

I was curious and I accepted the message - I fully expected it to be a prank and that I would receive Tub Girl or worse...

What I actually got was an image, an MP3 of the Coke theme and a 3GP movie of a Coke advert. (I figure if they're spamming them to all and sundry, I can distribute them as well...)

It's an effective advertising campaign. While I don't care for the mp3, I'm sure lots of kids will enjoy it. I even thought that the video was rather funny.

I'm in two minds about this....

1) I did consent to receive the advert. If I'd clicked "no" I wouldn't have been bothered by it again. It's pretty much the same as a Big Issue vendor asking if I want to buy a copy.

2) On the other hand, if every shop was blasting out messages, I'd be a bit pissed off. Rather than a couple of Big Issue vendors, I'd be assaulted by a team of chuggers.

However, in this case, I can solve all my problems by turning my bluetooth off or setting it to non-discoverable.

For now, it's not a problem. It's low volume and trivial to avoid. But what happens when someone starts hacking your non-discoverable phone and starts sending offensive images in the name of "Pepsi Cola"?

What would King Harald make of it?
