i recently purchased a spv m600. you can easily use the standard today screen. just go into the "today" parameters and uncheck the "orange" entry in the elements section.
i have done this and am happily using a standard today screen. however...
on the orange screen there is a cool menu for the sms stuff. it gives you lots of information about sms receieved, etc... i am missing this a little.
however, without the orange today screen, i can not find the sms program at all. i have been looking around, but have not found the executable to be able to launch or create a shortcut.
if any one out there knows where it is, it would be greatly appreciated.
