I prefer to do it at night (when kids are sleeping) in the bathroom :) If you have not dismounted a lens from your camera yet, now is the time to learn. Turn off your camera. Press the lens release button located to the left of the lens when the camera is viewed from the top, then rotate the lens clock-wise to dismount the lens as shown here.

Get a solder sucker and remove all the old soldering.

Retrieve/reset your apple ID password is the only way. This is a security feature to discourage phones being stolen, brute forced, hacked etc You'll still get $10 on ebay for it, they make great paper weights :^)
