I have had a few different ROMS on this phone, but it is malfunctioning right now (not related to flashing roms) and I have put a stock sprint rom on the phone, when I do to the dialer there is an icon of a padlock that is unlocked, what does this mean?

SHould I lock the phone back before taking it in for the total equiptment protection? Can they/will they detect that it is unlocked?
