Double boot after switching to android?

[ceibanez]

I haven't been able to find an answer to the following question.
Will it be possible to have a double boot on your phone after installing Android? Is anyone working on it?
Like in any OS you can never get everything you want in one place. Sometimes you just have to use another OS to accomplish a task without having to re-invent the wheel. (Just a random thought)

It's still early days, but i see no reason why this can't/won't be achieved.

Android will be released under Apache v2 license, so once you've got the source you can pretty much port it to whatever:

I would imagine that they'll be a race to see who can get the Android OS dual-booting on an unlocked/jailbroken iPhone before long
