Is pencil lead harmful to the inside of an iPhone?

Added (1). The reason I ask is because I have an unlocked iPhone 3GS. It was given to me by a friend who upgraded to a Samsung Galaxy. However, I was pretty stubborn as to use a #2 mechanical pencil and got a small piece of pencil lead stuck in the phone. Is this harmful to the phone? Should I be worried? It's a nice phone, and I don't want it to fry. I can't afford a new phone right now.

Not good.

Pencil "lead" is graphite, which is conductive. In the wrong place, it could cause a short circuit. You should use a paper clip to press any "reset" buttons with any electronic device.

There's nothing you can do about it now, except hope that the bit of lead doesn't get to a bad place inside the phone. Don't use a mechanical pencil again.

So i was attempting to open up my sim card slot on my iPhone 6, and i wasn't able to find a paper clip or anything metal that was small enough to fit inside the slot, so i attempted to used a mechanical pencil (yes i realize it was a stupid idea now) and the lead broke off inside of the slot and i have no clue how to get it out. Any help is appreciated, thank you!

  • Isn't it creepy to buy a band's lead singer's iPhone? The lead singer of my favorite band is selling her iPhone on Ebay and I wanted to buy it but I don't want to be creepy. She has a YouTube channel and asked if people would buy it and they said yes and so it's on sale now, but I don't want to buy it and tell my friends and then they call me weird or something. It is my favorite band and I was going to get an iPhone anyway, so I thought "why not?" Is it creepy or am I just being paranoid?
