Here’s an interesting iPhone hack if you are still using a Newton PDA device (I hope not!), to use iPhone as keyboard for Newton.
However, this could be very useful for adapting to other devices via iPhone’s serial port, there’s free schematics and code.
This app will allow you to use an iPhone or iPod Touch as a keyboard, to input text on a Newton running Newton OS 2.0 or later. You will also need an adapter to connect both devices together.
