And it's this type of false analogy that I find disturbing. They're not "broadcasting" it at all. How is using it as your default login account name "broadcasting" anything?

Most banks, when you first setup your on-line account, ask for the account number, and other identifying information in order to setup your account. How is that any different at all than this? Answer: It's not. In fact, it's not just similar, it's almost identical. And most make this interface public, where you can log in and setup your online account, as can anyone with that information, just like MyNokia.

All of your arguments here are assuming a lot of things: That the database where the information is being stored isn't encrypted or firewalled, that there's no hashing going on, and/or that they're in some way "broadcasting" all their usernames (and thus your phone number) out to the masses. They're probably storing that data just like most other services, behind some type of firewall, using SSL to get the name and password, and comparing it in a safe way.

Yes, it was wrong of them to take the info without asking. But saying that they're "broadcasting" the information, or making it publicly available when they clearly are not is just flame bating, and helps nothing.
