Ya I Did Back Them Up Bt There Was Some Error Restoring Them,,, Bt There Is No Method To Copy Suite Messages Back To Cell..

Yes you can! Simply drag and drop the message from Nokia Suite to the appropriate folder on your device shown in the bottom left. Remember to drag messages one at a time. If you drag and drop the whole conversations to say, "inbox", your phone would be full of both received and
sent items.
There is an easier way to accomplish this however in the Nokia Suite 3.3.86. Since it has the "Inbox" and "Sent" views, you can simply select the "Inbox", hit CTRL + A (Select all), then drag the messages to the "Inbox" folder of your phone shown in the bottom left. You can do the same with "Sent" as well.
Let me know how it goes.
