For me, it appears so, sucks because latest Google Voice is great and the sole reason I want to go back to 1.5 (and then maybe the root 2.1 etcs). EDIT: NOOOO! It's fixed. Confirmed for me, calls now show google voice number in latest google voice app! (as displayed in long list of fixes/improvements.) I definitely encourage any old Leak V2 users to upgrade that want the latest Google Voice!
