The final iphone sdk 4 is out( for a while ).
It's safe to compile with iphone sdk 4 final ?
Can this be done now with the last head files?
Also it's safe for lower versions of the iOS ( 3.x) ?
I think the Appcelerator folk are still ironing out a few bugs iOS4 has introduced, but at least for my app it seems to run well when built with the 4.0 sdk and the latest titanium_mobile from git.
