the iPhone Developer

This app takes what I have learned about in-app purchases and talking to web services and wraps it into an amusing little app which lets you send SMS messages to people in your contact list or any mobile number and have it appear from one of 12 defined senders, so in effect its anonymous. Now as it uses an online service there is a charge for sending messages which does *not* come out of your text bundle. Messages are 15p a time and you can top-up credits within the app. Showcase page is here.
