Got an older iPhone or iPod touch kicking around? Already jailbreak it for unofficial goodies? You can then install Android 2.2 as a dual-boot option on that device, through the Bootlace application available in the Cydia market. The Android packages download over the air, and you're left with a home screen icon that quickly reboots you into Android whenever you want to jump across the great smartphone divide.


Note from Adam: I've been following this Android-on-iPhone business pretty closely, and currently Android on the iPhone doesn't fully support power management, which means it's a hack more for fun than for practicality. When it is a more fully supported hack, though, you can bet you'll see a guide here.
