Colin, I went home and tested out the features of LightBlue, and i have to say, it is quite impressive. Very useful for debugging services and characteristics. If you started a new thread about this, I'm sure people would be interested in participating.
One things I'm curious about, or perhaps it's a feature request: I'd like to store descriptions about specific services and characteristics to label them, specifically custom ones that I am building. I didn't see a feature for this under the Central scheme. In other words, I'd like to define service 0xFF04 as a custom service with name: "HelloWorld", and whenever a peripheral is broadcasting this service, the iphone would see it as HelloWorld
