I find it actually very easy to do any hard reset using 2 hands. Here's the process I've used.
Take off the batter cover, position the phone in your left hand so that your palm can cover the entire phone. Place your pointing finger to the power button, and your thumb to the Vol down button. Now place the stylus in the reset hole, but using your palm to support the other end of the stylus. Then use your right hand to hold the ENTER button (circle button in the middle of the phone) and using your palm, press it gently on the stylus and it should invoke the process.
Have anyone tried to do this with only 1 hand?
