just reinstalling the registries found on my 928 and copying over the files, then you install the latest glance app and let it update, it will show up under "extras"
I saw a guy doing it on the 630 so I thought wth I just did it on the 928 after getting AU so rinse and repeat

its weird that DTTW issue you report actually happens to my 928 when I swype from hard left-right while viewing photos, after locking and unlocking the phone just wont respond to touch anymore, doesnt happen with DTTW disabled
