Get back from overclocking and see again. Overclocking is good but sometime may not work well.
Even after bringing it back to normal state, It is still better. The custom ringtones application doesnt seem to work anymore even after reinstallin it. I think some packages might have got corrupted causing some activities during call to get bypassed or something (Just a guess. I have no clue about Maemo OS as I am a noob in it.)
