I have my old sms in my N70 Nokia memory card. Now i want to transfer my old sms from to my N73 Nokia memory card. i do not have N70 mobile now, i only have N73 mobile.

Then install Fexplorer on that. N in that go to
c:\System\Mail.. Copy all of the contents of that folder n transfer it to ur comp. Then copy that "Mail" folder frm comp to n73's phone memory in d same location ie c:\system\mail..

Thanks for the reply but let me tell you one thing.

See the directory structure where all the sms's are saved in N70 memory card is N70\System\Mail...

but the directory structure in N73 (wot i saw) is N73\Private\1000484b\Mail2

and when i copy the contents of the mail folder to my N73's directory structure, no sms come to my phone when i plug my memory card into it. Please help......
