However, I have a suggestion for you. How about programming this number 1 button to your most frequently dialed number instead? If you frequently called your boss, why not program his number to this button? And for those who have aged parents at home, why not program their phone to your number? In an emergency, your aged parents only need to press the number 1 button to get you. There are lots of other ways, you can use your mobile phone to make your life easier.
