After a reflash, I got the "My Nokia" page. It gave 2 choices:
* Read agreement
* Done

I clicked "Done", because there wasn't a "Cancel" or "No Thanks" button. "Done" in my mind doesn't mean "Yes subscribe me" or "Yes start sending out texts at cost to me".

After I received a text from Nokia, I remembered from the My Nokia splash page that you can unsubscribe in the Settings dialog. I did this a couple of times, to be sure. Again, never having been informed that this was sending texts or costing me each time.

It's not a lot of money, but pretty shoddy behaviour in my opinion.
