I am trying to fix an Infuse with a broken lcd screen, I have seen on a few websites that there are different revisions of the screen. From 6.1 to 6.2 and so on. I have also googled the difference and have not found anything information out. Can someone please tell me how to tell the difference and how to identify the one I have. I do not want to order an incompatible lcd screen. Thanks in advance!
