Now with PR1.2 we have a Setting to subscribe to receive Nokia Tipps and Support SMS messages...

But for what are they useful? Today I received a SMS message that now a new firmware update for my N900 is released!

Damned, that was yesterday! It's a old message. And I have it already on my device. And I don't have to visit the webpage linked in the SMS message. I don't want to flash the firmware with usb when the ota update works so fine. And why they are sending such SPAM messages? The Application manager gives us all a yellow information mark that there is a update.

Should I cancel the subscription after this first annoying message or is it possible that there is something useful comming?

I can see it already: We all get before the end of the month the news that ovi maps has improved the poi feature with a nice link to a colorful webpage and the invitation: UPDATE NOW!
We are all clicking on the Link and 3 Webpages later: "Only for Symbian S60V3/5"
