Presumably iphone does Objective-C 2.0?

So given that Core is supported by the iphone are all the Objective-C
2.0features supported too?

So you can write iphone apps that use GC should you so wish?

I've yet to see the SDK which hopefully will answer these questions.

also given so much overlap b/w iphone SDK and Cocoa SDK do they coexist
together nicely or can you get by with existing tools plus frameworks plus
simulator?

Don't see any reason to have two copies of Xcode, IB etc just to do iphone
development.
