SMS backup problem (no timestamps) with Nokia N70

Hi all good souls here.

I own a new Nokia N70 mobile phone. I would like to backup my SMS
(short text messages) stored on the SIM card to my PC. So what I do
first is copy my sms (cca 15) from my sim card to the Nokia N70 inbox
folder.

But N70 is somehow not able to sort my copied text messages according
to the date/time criteria. If I choose properties of the corresponding
sms, each one has the date set O.K. so it shouldn't be a problem. But
forget this (I put it here just for some problem indication).

I installed recent version of PC Suite application on my win XP
computer. I connected N70 with PC with USB cable, and clicked on SMS
button and tried to copy them to my computer. They did. The messages
are sent to my PC, but with the DATE and TIME zeroed on each one, and
this is my problem.
As it is exactly what I need the most, to know the time and date of
each sms I stored on PC.

Any thoughts of how to handle the backup of SMS with the date and time
preserved? Is there some other application or freeware program I can
install that can do it for N70?

Thank you a lot for response.
