How to unlock the screen during a call?

[niky]

By default, when I place a call I have the touchscreen locked.
How do I unlock the screen?
Simply touching the "unlock" button does not unlock the screen.
I know it is possible to change the default behaviour to have the screen unlocked during the call but I do not like this setup.

I struggled with this as well, and then looked it up in the online manual;), the only way to unlock it is with the D-pad, the silver circle with the Palm logo in it. Navigate with that button to the unlock button and then hit the Palm logo, it will unlock screen and buttons. There is a setting in the Keyguard application (start-settings-keyguard) that lets you change this, simply remove the checkmark and the screen will not lock again.
