The GSMA Mobile World Congress 2010 is starting next week in Barcelona. It's going to be a huge event.

I got a text message like this from an unknown number:



When you click on the link, you get this page:



"During the installation, please click Yes to every question. You can trust this application: it's the official MWC 2010 mobile guide."

Oh, really? Just trust you because you say so?

And if you click for the application link, you get this:



Folks, this is not the way to do it. Just sign your applications instead of trying to convince us that it's ok.

We did check the application in question, and it is the official mobile guide. But it could have been anything.

P.S. Talking about Mobile World Congress, obviously F-Secure will be at there, so come and meet us. And I'll be talking about Integrating Security into Every Step of the Mobile Handset Design on Tuesday at 2pm.

Signing off,
Mikko
