K2 does not provide built in mobile to item functionality unless the mobile device is pretty compliant with the desktop browzers it was designed for. I have seen post from blackberries to k2 sites using k2's front end editing abilities, and have also seen extensions for joomla articles from email, but not k2 items from email
