GSM Stumbler UI prototype screenshot
Here’s my first step at creating a user interface for my GSM Stumbler Windows Mobile application:

It’s very basic right now. All it does is pull out the phone’s currently connected cell tower and logs it to a text box on the screen. This data can also be sent via SMS or HTTP to my website to update my current location.
Also today, I created a PHP script to update my current Jaiku location. This isn’t in place yet, but I eventually intend to integrate this into my GSM Stumbler application. Future ideas include: looking up the location as human-readable format on the device, detecting multiple nearby base stations and their signal strength (for triangulation) and more Jaiku support.
