Version:           kmobiletools-0.4.3.3 (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
OS:                Linux

with kmobiletools-0.4.3.3 (cant compile newest version  ) 
kmobile stumbles when trying to select memType 'MT' for sms on my p990. 
test command for Preferred SMS Message Storage returns:
at+CPMS=?
+CPMS: ("ME","SM"),("ME","SM"),("ME") 
OK
with p990. so there is no memtype 'MT'as hardcoded in kmobiletools.

my quick and dirty hack is to change line 45 in c_config.cpp from 
addItemStringList("sms_mem_used", sms_mem_used, (QStringList("MT"+="ME"+="SM" ); 
to 
addItemStringList("sms_mem_used", sms_mem_used, (QStringList("ME"+="ME"+="SM" );
