## What it is
A collection of supporting tools for running Android/Linux on the iPhone, including a kernel loader via pongoOS, a syscfg partition extractor, a touchscreen daemon, and a Bluetooth firmware extraction tool. It is part of Corellium's Sandcastle project, which also provides a custom Linux kernel fork and Buildroot-based ramdisk.

## Use cases
- run Linux on an iPhone
- boot a custom Android kernel on iPhone hardware
- extract syscfg configuration data from an iPhone
- extract Bluetooth firmware from device binaries
- get touchscreen working under Linux on iPhone
- rebuild Android native libraries for 16kB page size

## When to choose
- you want to port or run Linux/Android on iPhone hardware
- you need low-level utilities like kernel loading or firmware extraction for Apple devices
- you are building a custom Linux distribution for iPhones with Buildroot

## When to avoid
- you want a polished, user-friendly way to install Android on an iPhone as an end user
- you need support for modern iPhone models or recent iOS versions
- you are not comfortable with low-level device hacking and kernel builds
