So does that actually work?
I've been an iPhone user for less than 2 weeks. One of the first things I read is that you can double-tap the Power/Lock button to end a call. I know we're able to do a two-finger double-tap to end calls, and that works for me most of the time. But ending a call with the Power button has me intrigued, because I've tried it several times and wasn't able to get it to work. The only time I seem to be able to get the Power button to end a call is if I take the phone away from my ear (which changes it over to speakerphone), double-tap the screen to unlock the phone, and then press the Power button once. Pressing it while the phone is to my ear only seems to put the call on speakerphone.
