You can try, menu > settings > applications > all > dialer (which version you're using now) clear defaults.
Did what you guys said...but not working
When I push the phone button on the home screen the stock dialer comes up (i want dialer one)
Then, when I touch the little phone icon on the bottom right is when dialer one comes up.
How do I get dialer one to show up immediately when push the phone button on the home screen?????????????????
