Hmm, it seems that this is a great app, but I'm a little suspicious. (Sorry for that.)

• If it updates the camera firmware, does it change it back when uninstalled?
• Exactly what does it do with the camera firmware?
• Does the Camera app receive any benefits of all these stuff?
• If I don't want HDR (because of the time needed to process it), can I turn it off?

Anyway, why don't you upload it to extras-devel?
It would be much more easy to update it, for all of us.
