Uunder iPhone OS3, you had the option to set the double click, in the accessibility settings to various options like Phone favorites. Of course under iOS4, the double click brings up the multitasking task menu. However, this came at the expense of a usefull feature. I was able to get into my phone favorites with a double button press instead of clicking home, pressing phone book and then pressing favorites. There was an option under iPhone OS3 and iOS4 for a tripple click. But these are still the same limited options. Why didn't they just add the ability to set it here then to what you want. I'm sure most people don't use the tripple click. Unless there is another setting I am missing to allow you to quickly bring up phone favorites or another program, etc.
