I have just followed the instructions in the following link:
http://www.modmyi.com/forums/native-iphone-ipod-touch-app-launches/436851-bitesms-intelliscreen-quickview-2.html I manage to get smartDial to open BiteSMS.......but it doesn't start a new SMS Message with the recipient that was searched using SD.
hmm.. there isn't much more i can do. The only way for me to launch SMS is to send the OS a "sms://5551212" type message and it does the rest. The API doesn't allow me to do more.
