I just got an email from Canon:
Canon has released a firmware update for the EOS 60D Digital SLR camera.
Affected Product
EOS 60D Digital SLR
Firmware
Firmware Version 1.1.0 incorporates the following fixes and improvements.
1. Fixes a phenomenon where the wireless built-in flash settings are reset to defaults when the battery is removed from the camera.
2. Fixes an intermittent phenomenon where image-rotation information is not recognized correctly when shooting with the camera in the vertical position depending on the timing of the shutter release.
Firmware Version 1.1.0 is for cameras with firmware up to Version 1.0.9. If the camera's firmware is already Version 1.1.0, it is not necessary to update the firmware.
The new firmware (Version 1.1.0) can be downloaded by clicking here.
