is there any way to make the Device more Secured !?
I mean with the full built-in Keyboard, wouldn't be nice to have an alpha-numeric based code and not just a numeric one ?!
(maybe switch between the two modes from lock code settings)
and it's really annoying to see the entered key before it turns back to a star !!
anyone agrees with me !?

I agree. I would also like to see portrait mode support added to the lock code screen (and to me this is higher priority than alphanumeric passwords, but that would be nice too).

But I myself lack the coding knowledge, let alone Hildon knowledge or Maemo 5 in-general knowledge to know if it's closed/open, or if an open source clone could be feasibly made.
