I understood about the dealing with the pinout. That's not much of a problem. I've been having difficulty for daylight viewable applications. Nobody seems to make available Transflective screens in Mipi DSI.
However, I believe I have found a solution which I'm working on Pursuing. The iPhone 3 / 3gs has a highly transflective screen and the iPhone 4 is less reflective but still transflective. The daylight viewability of an old iPhone 3 I found at work is actually staggeringly good. Well pas some of the cycle computers out there.
