Search Contact doesn't working in iOS6 (v 3.0.3 alpha2)

[GoogleCodeExporter]

Hi,
I'm using KuaiDial 3.0.3 alpha2 in iOS 6.1 in iPhone 4 GSM.
I switched on "Enable Search" in "Keypad" section but seems that "Contact 
Search" feature doesn't working anymore.
My mean as "Contact Search" is when I dial numbers, search contacts and show me 
related contacts which contained those numbers same as other smart phones have 
(also "phonehint" tweak had in iOS 5)

So, I have 2 questions:
1. Does KuaiDial have this feature?
2. Is it working in that version and in iOS6?
