Free to send software for pda

TalkSender 3.00.1006 offers you a professional but simple and easy-to-use program which can allow you to send vocal emails without having to perform any configuration. You record your vocal message by pressing a button (the format is .mp3), you then set the destination and the text of the message and then a click to send it, after connecting to the Internet, of course. Nothing could be simpler.

This system extension allows you to send short text messages from applications supporting the "Send..." command, for example the built-in Contacts, Memos, Calendar, Tasks.
Compatibility
Tested on Treo 600 and Treo 650. Should work on Treo 700p as well
Theoretically, it can also send SMS on other devices if there is an SMS-handling application registered in the system.
Usage
Select "Send..." from the menu
Select "SMS"
The text is pasted into the message, now you can fill in the "To:" field and click Send
Limitations
It can only send Text, exactly like if you typed it yourself. The receiver will also get the data as text only. For Memos this is obviously not a problem. For Contacts, Calendar events, and Tasks you can use RNS: TreoVCardReceiver to automatically transfer the incoming data into the associated application.
The amount of text is limited by the medium, you cannot send more than a few hundreds of characters.
And of course no binary data (it would be hard to find the binary file to match the size limit anyway).
What about the built-in Messaging/MMS?
On the Treo 600 you can send this kind of data with the built-in MMS application (call "Send", pick "MMS") - but there is no option to select SMS instead of MMS. On Treo 650 it is called "Messaging" instead of MMS and it is even worse (all you get is: "The messaging application does not support this type of item.").

- Palm OS 4
