[WTB] iPhone 11 Pro 64GB on IOS 13.0 - 13.5

Hey all. I'm looking to buy an iPhone 11 Pro on one of the iOS versions:

13.0
13.1
13.1.1
13.1.2
13.1.3
13.2
13.2.2
13.2.3
13.3
13.3.1
13.4
13.4.1
13.4.5 Beta
13.5
13.5.5 Beta

Reason? Jailbreak purposes. Also looking to upgrade my iPhone X.

Preferably 64GB but will still consider 256GB.

Colour shouldn't matter but would love Gold/Silver.

Prefer to come with original box and accessories.

Budget is $900 max for 64GB.

Let me know your phone and asking price regardless as I would like to know my options.
Thanks!
