Yesterday i made a little searching for tweaks for my k810 and found this site with great menu icons.
I belive they have other great stuff for SE but unfortunatley i am not that good at russian so soon after finding good set of icons for my phone i lost will for more searcing.

Here is the direct link to the icons section,for easier finding.
