ModemManager PUK-locks sim cards if the wrong PIN code is entered once

[Torgny Johansson]

If you have a PIN-locked sim card and enter the wrong PIN code when prompted, ModemManager will immediately do three failed attempts to unlock it which makes the sim card PUK locked. Note that you only have to enter the wrong code ONCE and this will happen. Expected behaviour would be to only do one attempt and then ask for the PIN code again.

MM version: 0.2.git.20090909t142854.64b7be7-0ubuntu1 on Kubuntu 9.10.

the problem that made mm lock you SIM when entering a wrong PIN is fixed. There are some other issues sourrounding PUK handling left, that I put into bug 449401
