Is there a problem when downgrading the phone from 2.06 to 1.78 ?
I have issues with 2.06, sometimes workouts are not stored correctly in my E71 and do not appear in the calendar. A file was created, but it seems to be not valid.

So i decided to go back to my previous used version 1.78.

Now it looks like all workouts are displayed in the calendar, but the ones created with 2.06 do not show up with route-display, instead only a black screen is shown. The very old workouts stored with 1.78 can be shown....

Does anybody know if this is correct?
