Is it possible to import SMS into a folder?

I'd like to write an application which can import text stored in a text file into the sms folders.

To, From, Received and other properties of a New SmsMessage() are read only - is this a restriction of the WM5/6 API or is it just not implemented in your component?

You can write directly to properties on the message using the Properties collection e.g.

 sms.Properties[MessageProperty.SenderEmailAddress] = "John Smith <123456789>";

The MessageProperty enumeration contains all the supported properties such as MessageDeliveryTime (Received). To modify the To recipients you can add new Recipient objects to the collection, then call Update() on the message to save changes.
