> Utterly staggering at the lack of imagination ... nearly 11% of the 3.4 million passwords are 1234 !!!
Not so staggering. Those people probably did not want a PIN to begin with. I know someone with the PIN 1234. Why does she have a PIN at all? Because the phone requires it to store Exchange credentials (if I remember correctly). I've suggested it changing it to 1111 because it's even faster to type, but she never got around to it.
I too have a pattern lock, the simplest one I could come up with. Easily broken. Why? It's required to store VPN credentials in Android.
And there is a second advantage: by trying a PIN, even a default one, you are gaining unauthorized access to an automated system. This is illegal by Dutch law, even if the only security was a warning message on the lock screen saying "Do not unlock."
