If you can get past the cheesy hosts, this interview by This Week in Android actually has some decent information on planetbeing's going's on's to get the iPhones running Android.
EDIT: The relevant info is at 23:02-32ish. The rest is loooooong.
Notable points include this port being 2 years in the making, 8 months of actual active working on it, as well as his attention also being quite focused on getting Android to 3G[S] - as it is his personal phone and he'd love to be able to use both platforms on his primary device.
Wang also says his goal is not to have a "gee-whiz" implementation of something cool and geeky, but an actual, full-time useable Android implementation on iDevices.
