Bootlace lets you install Froyo on your iPhone without a computer
It may not solve some of the problems involved with actually running Android on an iPhone, but the recently released Bootlace 2.1 application for jailbroken iPhones does at least make the installation process easier than ever. Unfortunately, it only works with the iPhone 2G and 3G at the moment, but it will let you install Android 2.2 (a.k.a. Froyo) directly on the device without the need for a computer. Hit up the source link below for the complete installation instructions — and insert your own joke here about the iPhone running Froyo while your Android phone is still stuck at 2.1.
