If I factory reset my iphone will all my contacts be deleted?

Yeah, factory reset will give you a new phone except its appearance, so all your data you put in will be lost. Before you do that, just make sure you have backed up all your important data. Or else, you may have to turn to paid professional data recovery software to help get back.

"Factory reset" - to clear a device to the state it was in on leaving the factory. Were your contacts in the phone when it came from the factory? That should answer your question.

Yes. Factory as in as it came from there. Of course it didn't come with anything on it

Yes if you don't make a back up. No if you do. I suggest making a back up though iCloud on your phone.

Yes everything in your phone will be deleted but anything that is in SD card will not be deleted. Take factory reset very carefully.

Yes, but your contacts can be recovered by tool easily. If you want to permanently erase all your contacts for privacy protection, try this iPhone cleaning app: http://www.safe-eraser.com/

Hope it helps.

Factory reset will delete all things but not the data of SD cards, so beware, safer is first move all the dats to SD card and them reset.

Yes, unless you did a backup
