dCaller ID program

Which do you use, if any?

I forget which one it was, but I downloaded one that had high ratings once and it CLEARLY lagged my phone...as in, when I get a call it would instantly show up....with this one the screen would be black for a few seconds before it would pop up (but it would still be ringing)...

Anyone use these or do they all lag your stuff?

PS - I have no clue where that D came from in the title. hehe
