Updated iPhone and Arduino code to work with firmware v1.1.0

This fixes *some* of the issues from [Issue 4](https://github.com/michaelkroll/BLE-Shield/issues/4).

Changed to the new baud rate, 9600. I tried to use the new UUIDs from this [blog post](http://www.mkroll.mobi/?p=10550), but they weren't all correct. 

Changing the baud rate doesn't work either, so that characteristic may be incorrect as well. Can you please have a look? Thanks!
