I'm desperately trying to find this info and have been searching for several days. I use wifi + skype on my iphone with no plan. All I want to do is when I click on a number in a web page, or in the contacts, is have that number open with another program like skype or google voice.
Is this possible or is there just no way around opening a number with the default dialer? I figured somewhere there's a value that determines which program is called to dial a number.
