To use SMS Templates, just tap on a template, then you can choose to straight ahead send the message, or pick a contact to send the message to. The Messaging application will then start. Double tap the message body and tap Paste, to paste the template into the message body. Tap Send to send the message!
SMS Templates comes with some predefined templates, including messages with emoticons! (Emoji for the Japanese public).
Note - you may be wondering why I didn't just start the Messaging application and prefill the message body automatically. Unfortunately, the iPhone SDK does not currently support this functionality, but I will update the application once it is available.
