Flagged IPhone Device iD

Hey Guys,

i know that iPhones can be flagged by Instagram and shadowban the account. - I’ve been there.
So for my new account i bought a cheap Android phone and a sim card and check the instagram app only via mobile internet. It works perfectly and no shadowban in sight.

However I just got a brand new iPhone yesterday and wondered if i could put Instagram on the phone? I heard though that setting it up with the old Apple ID could flag the device again? Is that true?
Do I have to create a new apple ID?

I’m scared of messing up the account as its growing like a charm.

Thanks a lot guys :)
