You can always view them from the Profile.
However, I've just done a test, and exported a .map file from the SatMap for the trip I did last Sunday. It converted it to a .gpx, which I renamed and saved onto my PC. I then imported it back again, and then selected View and Profile and all the data is still there.
I can also open the file on the PC in Notepad, and it shows all the individual bits of data. For example from last week:-
<rtept lat="51.407808220710937113974061949" lon="-0.3653788012453831430711208658">

The oldest file I've got saved back onto my PC is from April 2011 and it's the same, so I don't know if they changed something in the past (I've only had mine just over a year).
