PocketCM Contacts is approximately a billion times better than the stock contacts manager and it's free. It scrolls perfecty, gives you access to all numbers and email addresses, and also becomes your stock contacts manager after you've installed it and done a soft reset.
I have it mapped to the right soft-key on my Home screen for easy access. For some reason, PocketCM doesn't show up in the list of applications available to Diamond Tweak to map to the soft keys, so I've used Resco Registry Editor to do it.
Hope that helps!
