Sorry for bumping this 5-months old thread...
I installed this on a friend's Sony Ericsson K750 (latest firmware version I think).
It installed fine, however, when I open the application, I can't send the message.
There is a textbox to type your message, however, I find a way to send the message.
Tommorow, I will try with a K700, and tell if it there is a way to send the message.
For those who tried it with your K750, how do you send the message?
By the way, the feature that sends the message to the receiver that BT can't reach using a receiver that BT can reach is not implented yet eh?
Kinda-offtopic: The site's MIME types should be changed about JAR and JAD files: I tried visiting the site with the phone, and all I was getting was text!
Sorry for asking so many questions...
