I am having the same problem. I know about being able to set the call log as the primary screen when I open the phone, but I'm not interested in that. I need a dedicated button to access the call the log and another to access the dial pad. In the past the green phone hardware served to get me to the dial pad and the call log button has served to get me to the call log. I have contacted blackberry for a possible fix and am currently looking for a third party app to fill the role. Unless I find something soon I'm going to have to go back to a previous version of the OS. I'll let you know if I hear anything from either of those sources.
