Bootlace is an iOS application for jailbroken Apple devices that allows the installation and configuration of the open source bootloader OpeniBoot and Android based operating system iDroid.
Bootlace is programmed natively in Cocoa Touch and runs directly on the iOS device requiring only an internet connection. Currently Bootlace supports the iPhone, iPhone 3G and iPod Touch 1st generation.
You can install Bootlace through Cydia as it’s hosted in the BigBoss community repository.
