If you have an iPhone but find yourself lusting after the Android OS, then you might consider cramming Froyo onto that piece of Apple-branded machinery. And, thanks to BootLace 2.1, you don't even need a computer to install it.
Only compatible with iPhone 2G and 3G, BootLace 2.1 requires users to have a jailbroken iPhone before they can use it. If you used PwnageTool, Redsn0w or Blackra1n to hack your iPhone then you're in luck, your phone is basically ready to get its Froyo on.
This isn't the first time that Froyo has been, shall we say, shoehorned, onto an iPhone. Unfortunately it still doesn't run quite as smoothly as it does on the likes of the Nexus One, or any other device built for Android, but you can at least use it to make your Android 2.1-toting friends green with envy.
