are you rooted?

 

Wouldn't you hose your phone. Even dailer one uses..from what I seen..the dailer interface during a call.

 

i tried doing this after first installing Dialer one a few months back (well actually tried hiding phone.apk by renaming it in Terminal), and it resulted in FC city. Dialer one is just an alternate dialer/contacts/recent calls interface, where phone.apk is responsible for actually making and receiving the calls. Dont do it lol

 

With Samster's post, the answer appears to be a definite NO. But thought I'd add ... whenever you want to try to get rid of any stock app, the best thing to do is a nandroid backup first. That way, you can revert back if things go south.

A lot of apps are only frontends to the stock apps. It sounds like Dialer One is one of them.
