I found out a few days ago that my Nokia E90 has a similar feature. If I misplace it or some scumbag steals it, I send it a text message and it will lock up the phone. Only problem is: will I remember my password if it ever happens to me?! Actualy, what is the password?

Hopefully it’s not just a standard phrase in the text message. Otherwise it would be fairly easy for me to sms someone’s computer with “Lock Down” and make their day very difficult. I also hope it’s an easily reversible process, but not too easy to undo :)

I agree with Rick full disk encryption is the way to go.

It’s an interesting sounding gimmick, but I think I would feel more comfortable with whole disk encryption plus two factor authentication.
