OK, I dirty flashed earlier (sorry! Didn't see your reply!!!) and, as a matter of fact, I'm still experiencing a lot of ram being eaten (although, as of now, around 190mb are still free...) and camera keeps on behaving strangely (take a picture, but then pic is not saved and screen is frozen on the "not-taken" pic until you exit the app).
But yeah, once again, might be my fault actually.
I'll try and see tomorrow whether a clean flash will do the trick (but hopefully some other user will have tried that out!)
Bedtime for me!
