For those of you curious: Tablet-UI does work on JB. simply change your dpi to 192 and reboot. Since there are not much big tablets available, i'm not sure if the launcher is supposed to stay "normal" but the icon grid resizes, and the notification menü changes a bit.
Most changes are in Contacts app and in GMail (Two Row Layout). Also i'm not sure if two-row-layout in Settings is supposed to be missing or any other bug is appearing. Would be nice if someone with a nexus 7 could confirm the one row settings dialog.
No other fixes needed. You might want to change text size to biggest. Then it works like a charm.
