I see that a version of Froyo for the Droid has been leaked that is newer than the OTA version FRB01B. Will SS4.7 be using that leak as the basis for proprietary files? Early reports are that the UI is "snappier" with this version - maybe it will address some of the redraw issues with the various launchers (Launcher2, LauncherPro and ADW).
Edit: I see that another thread has already been started on this issue. Thanks.
