Switching phones and getting the same minecraft pe edition worlds?

So I'm getting a new phone,
And I play minecraft,
I've done way too good to just get rid of it so if I get another phone (iphone to be exact) and download minecraft pe with the same Apple ID, do I still get my same worlds back?

No, you don't. I'm pretty sure it's saved to documents and data, and not to the app account.
