I am not the original author of BBWeather and these changes are not supported by the admins of the blackberrytools website. The source code is available so, at the prompting of Stinsonddog, I made two small changes: 1) Alt-Space works as a shortcut for the "Update Now" menu item and 2) Profiles are now sorted alphabetically by description. These were the only changes made, so if these two features do not interest you, then there is no need to upgrade from an older version. If you can't get the original BBWeather to work on your phone then it is likely that you will also not be able to get this version working.
