There are no buttons at all, just "enter your password" followed by "incorrect password" I typed it in very carefully, because I've been caught out that way before! After three errors, it said "Try again after 1 minute" next time "Try again after 2 minutes " then try again after several hundred thousand minutes, so I can't even try any more things I might have mistyped.
I can't find a pinhole to stick a paperclip into either, to do a hard reset and lose everything saved (phone numbers, email addresses, notes, internet links, messages)
Apparently Nokia are very security conscious, so that thieves can't unlock it!
