Can someone with Gingerbread try performing a small experiment with the Call Duration issue? I have yet to upgrade, and don't have access to an Evo with Gingerbread. Anyhow, can someone try going into call history and choosing a random entry and doing a long press on it. It should bring up a menu, with which you can select detailed call history. If someone can check if that option is still there, and if it is and you click on it, does it show call duration there?
