I have a contact shortcut on my home screen and when I click on the button to email him, for example, two options come up, and if I wish, I can ask the system to remember the chosen setting. I did this a while back for his phone number, so that it will call his mobile straight away. However, I would like to undo this so that I get asked which number I want the phone to call... I can't figure out how to undo this, however. Any help? Thanks!
