I have over 600 contacts (I have built a huge list at work). I had a pretty big contacts lag problem before 2.1. After 2.1 it is much better, but when I open the contacts app, I still have a few seconds of lag before I can scroll. However if I click Phone and get to contacts from there, it is instantly ready to scroll (except after a phone reboot, it does lag the first time). I take it these are truly two different programs that access contacts, and the phone one keeps running in the background while the contacts app shuts down each time. Anyone notice this?
