On my T600, T300, and all of my visors I could change what day I wanted the week to start in the calendar. I got my new T650 today and while trying to set it up I noticed that I cannot pick what day of the week I wanted my weeks to start on. It is set for Sunday default. Anyone know if it is possible to revert back to an older version of the datebook app or is there any way to add this function?

Maybe there is some other reliable datebook replacement I could use?

I know this sounds like a very petty issue but after so many years of having my week start on monday it is tough to make such a big change (please detect the sarcasm).
