Hello! This post is related to Project Alpine: Remastered, and is all about interaction with the iPhone. And that’s what I’m going to discuss.
However, this software is a work in progress, so don’t mind anything you see that may be for Apple-internal use!
Introducing MobileDevice, the next step into interaction with the iPhone in Roblox. This means you can allow your games and apps to implement restoring, updating, tweaking, etc.
A little tip: This is my first OOP script!

Your feedback is greatly appreciated! 
I’ll work on a dummy device for you guys to test out MobileDevice on in the meantime! For now, I’m working on ramdisks that allow you to transfer files from iBoot into the root filesystem.
With great love, Opuqide
