so I updated my Samsung i5800 to Android 2.2 (Froyo XXJPM) following instructions here.  http://chrisnoble.wordpress.com/2011/06/07/android-2-2-froyo-on-my-samsung-galaxy-580-nz/

This all works fine and dandy, and in general I'm very happy with it.

BUT I have noticed a major flaw in my plan.

I can no longer receive inbound calls.  The call will sometimes hit my phone, often vibrate, sometimes ring and even sometimes show who's calling.  But I never get the chance to fix pick it up

Outbound calls work fine, as does web, txt, and everything else.

Any ideas to try before I roll it back and do a factory reset?
