I rooted my old phone HTC Desire HD today. I did a S-OFF and flashed it with Cyanogenmod. The phone has become fast, which was not before with HTC sense 3. The only thing I missed was swype and getting contacts by dialing there name.
I got through this installing swype beta, and Dial-pro from Google Play. Pictures below:
Update: Cyanogenmod 7.2.0 RC1 has new predictive contact. Swype was removed because of high memory usage.
