hi all... can anyone recommend an ICQ application that can properly show you in 'invisible' mode for my Treo 650?

many over in the 650 forum seem to love VeriChat, but i've found that it does not actually keep me in 'invisible mode' when i am online, i have had friends confirm from their clients that i am visible...

any other suggestions? i don't need any other type of IM functionality, i use ICQ exclusively..!
