What type of handset is it?
Have you the sms set up in conversation mode and not separate folders ie inbox, draft sent etc
Have you tried checking your SMS settings.
Some Nokia mobiles by default are set not to save sent SMS.
I have used android before with htc desire and never had this issue all be it it was an earlier os.
