I have upgraded to DXHH3 firmware and the following are my findings:

a. No new software found

b. Response time of screen tilting is now faster and with more animation

c. Previous bugs:
- touch vibration: previous version, part of my screen do not have the vibration but now after half day testing the whole screen has the vibration when touch :)
- death screen: so far so good as no death screen even on widget today screen

Other problems:
My mistake, I restore the wrong mail/messages database and corrupt some of my earlier mails (all emails before lunch are now deleted from my server)

Will update when play with it over the weekend.
