i am using my device with the leaked PR 1.2 and everything is working fine.

though 2 apps/widget stopped working; namely "personal data monitor" and "conversations" widget.

the "virtual keyboard" sometimes annoys me (maybe due to being used on the old one)

the menu icons are fully customizable.

overclocking still works, BUT!!! be warned! the only way I see to revert back to the stock kernel is a re-flash!

even @ 600mhz, scrolling is smoother even after days and weeks.

there is a way to re-enable non working repos in the leaked version IMHO. what i did:

-no apps were installed (or my apps are not yet re-installed
-disable extras, extras-testing and devel

-update (install updates if there is any)
-"restore apps"

-enable "Extras" repo then update (install updates if any)
-tap "restore apps"

-enable "Extras-Testing" then update (install updates if any)
-then "restore apps"

-same goes to devel, update then restore apps

i have successfully re-install my apps from PR1.1 at the leaked PR1.2.

-there is now the e-mail widget.
