Build date is found on the inside of the back cover. Mine reads "DT10.04.26" I have a Version 2 Not exactly sure what the DT means, but the other numbers mean it was manufactured on 4/26/10. The DT could be the place of manufacturing? Or the line. Is anyone's different? This Poll is to try and figure out when the version 2 ended, and the version 3 began. It is also to figure out when the screen change was. Thanks to owl, we have a guide to finding your screen type!
