IDroid

iDroid is a project with goals of porting Linux and Android to iPhone, iPod touch and iPad and use different OSes as alternatives to standard iOS.

iDroid is not actually a hack/exploit neither an unlock, but it is based on Bootrom exploits which allowing the running of unsigned code at low level.

OpeniBoot
The goals of OpeniBoot are:
 * to run low-level code
 * to have low and critical drivers (NAND and NOR driver, NVRAM...).
 * to have a debugger and development environment (chainloading, upgrading itself and USB mass storage).

Linux
A Linux Bootloader, a working Linux kernel (cross-compiler), porting drivers, run Wi-Fi and command line through SSH.

Android
On 2010, an Android distribution based on iPhoneLinux called iDroid was released.


 * Announcement on the linuxoniphone blog: iDroid initial release.
