Caller ID Question

[pallen]

This might be the dumbest question I've ever asked, but I been doing some searching on CallerId here and on Modaco and havent figured this out yet.

I am running Adrynalyn's 2.0 CF03 ROM. I have been using S2U2 for CallerID, but today something wierd happened. Someone called me, and instead of S2U2 catching the call and showing the CallerID screen as usual, something else did instead. It looked like the new WinMo 6.5 lock screen with the same style slider. It had a slider for answer and a slider for ignore and the callerID pic. I didnt get a chance to get a good look at the screen though because i needed to answer the call, lol.

What was that and how can I enable that? I actually liked it better than the S2U2 callerID I have been using. I assume its part of WinMo 6.5, but I'm not sure. I have called myself several times with S2U2 unloaded and loaded and with different settings to reproduce it, but I havent been able to. I either get the S2U2 CallerID screen or the "classic" windows mobile notification style popup at the bottom.

Am I completely dumb here? I feel like I should know this, but I've missed something somewhere and not even sure how to search for it.
