encryption

yes it enables encryption in Security menu

I have started the encryption, and the phone shows the Eragon bootlogo loop. logcat shows:

runs already an hour, so I don't think it is actually encrypting...

Have also tested in Safe mode, the result is the same as in normal mode - does not work.... The blow test is also made after setting a PIN for unlocking the device...
