No more iphone support.....

Yeah I thought so. What features can you use? Are the tilt features available?

old style Tilt and multi touch yes, gyroscope no.
(so you can tilt but its not as precise and limited regarding axis etc, too)

I totally agree with you Adobe is in a very good position to screw this up if they don't keep up with the features current like other middleware's do.

yup

The only reason I ask because rather then port something I'm working on with unity or in xcode it's so much more convenient to be able to export it from flash, but I was only thinking if I could come in and clean up some performance issues myself, unless adobe eventually does it for me.

yeah, no tuning afterwards, as i said, its a final app what gets dropped out there.
Regarding performance: it was ok for some 2D stuff (though clearly again not anywhere close as native or other middleware made results) as long as you used all the flash typical performance trickery (ideally use no vectors at all, use cacheAsBitmap where appropriate, though best do all bitmapdata based and do heavy object pooling etc).
As soon as you had some other performance intensive things besides the graphical side going on like playing lots of sounds, a video, intense action with complex AI or physics sim going on etc it usually ran quite poor though.
Now the newer devices have faster cpu/gpu combo and more ram so that would help, on the other side the newer gen of devices also has way higher resolution so way more pixels to fill per frame, so yeah, would have to see if its good enough for your use case.

Also the CS5 exporter only supports iphone/ipod resolution and not ipad?

The last official version was released before there was an iPad or iPhone 4/ newest iPod touch with their higher resolutions, so yeah, other than obtaining some beta level stuff you´re largely out of luck right now.
Same with other iPhone device and OS features introduced after the last official Adobe release like in app purchases, Game Center, fast app switching etc.
