Lol you have an iPhone 3? All my kids 10, 12, and And 15 all have the iPhone X

Memory stick? You can't use that on iOS.

You can e-mail the contacts to yourself. I believe you can also transfer them when you do an iTunes backup on your computer.

There was never an "iPhone 3" which was also a smartphone referring the 3G & 3GS.

Contacts are usually synced through accounts, not something that could be transferred to memory sticks.
