I posted a previous concern over .90 now I found 1 additional problem. Previously I noted that this update does not fix the "media card inserted" message on re-boot that then leads to the verizon wireless logo that does not go away. Unless you pull the batter again (and sometimes again, and again). I have started pulling the media card with the battery then once the device is back up and running, re-inserting the media card. Just faster than booting again and again, sometimes. This is one issue that really needs to be addressed.
I have also noticed that yes the camera is much faster, however it is not saving the pictures anywhere that I have found. Checked options for the camera and it says saving pictures to the media card. But they are not there.
Might downgrade from .90
