Do I need an anti static wristband for repairing iPhones?

It's always a good idea to minimize static electricity when working

on delicate electronics. Myself, I just stay put and finish the task at

hand and avoid walking around and shuffling my feet on the carpet

which generates static electricity. If it's a day when you are throwing

arcs-n-sparks when you touch car doors and doorknobs then I tend

to be even more cautious that day. But in any event, I do not use

a wrist strap nor other anti-static grounding measures.

However, consider thyself warned and if you blow something up

because of staticE then it's your fault and you knew better.

Better anti-static wrist straps have a ground prong that you plug

into the ground of the AC outlet. Then you have a clip lead that you

attach to the device chassis via an alligator clip.
