iam developing an SMS application using Nokia PC connectivity SDK using VC++/COM.

I have two doubts:

A)How Many phone memories are there in a Nokia Phone?
B)I have used the GetCapasityinME() method for development.i assume this method gives the total memory capasity in Phone Memory.But this method is always returning 0. any ideas????????

Pls let me know th details at the earliest as it is very urgent
