Is there a way to adjust the color temperature on the screen of the Xoom? I am a photographer and one of the reasons I bought the Xoom was to be able to take it out to clients and use it as a portfolio of my photos. Unfortunately, the color temperature of the screen is so far off that all the photos I put on there have a very deep blue cast to them (I have seen the same problem on almost all LED/LCD screens used on laptops and desktop computers until they are adjusted). Is there an App available to calibrate the screen's color temperature?
