No dice. If it is a downloaded app after the handcent install I can...but for system ringers it won't ask me to choose handcent...it just defaults to stock
Oh ok, I get what you're trying to do now. I know GOSMS gives me the option to use it as my default ringtone chooser. I'm not familiar if Handcent has the same option. Try installing another ringtone chooser and see if you get the option to choose.
