Opinionated comments on mobile phone industry news

I present a scenario here to highlight that the most basic and needed functionality doesn't work on mobile phones.

The scenario is that I hate telemarketers, and I wish them all to hell, or at least out of my hell (sorry, hair). There you have it. I think you can guess I've had a bad telemarketer week.

So what to do:

1. I want all calls that don't present the number of the caller to be automatically filtered out, so I don't hear a beep from the phone in such occasions. It shouldn't even show up in the "who's called" list, as I can't do anything with it anyway. If a bona fide person has such a setting they will sooner or later contact me some other way.
2. If there's a valid phone number showing up, and it's not in my phonebook, the phone should immediately look it up in a trustworthy Internet-based number service. If it says something like "Sloppy Joe's telemarketing scam" I would with one key press put that number on the ignore list, and it should be treated as 1. above. The same if I take the call and then disconnect.
3. If it's a call I'd like to take, the information from the Internet service would be put in the phonebook.

Can this be done by default on mobile phones today? No.

Do fixed-line VoIP services and phones provide this? Yes.

Is it possible to write an application that does this? I guess in Symbian OS and Windows Mobile it would, but definitely not in Java.

Anyone seen such an application?
