UDID+ at first glance doesn't appear to do much, but the handful of things it does are so useful that this app will become a must have for anyone that regularly needs access to UDID for testing or custom installations. Combined with a bevy of other information provided by the developers on the same screen and a single-tap interface to access any of it, UDID+ is a great tool.
When you open UDID+ for the first time, you can see the all-important UDID onscreen right away. You can copy it to your clipboard or you can tap the "Send" button for it to be automatically copied into an e-mail so you can send it with a few quick taps. The tool goes beyond that, however, offering a battery meter and percentage reading, and a laundry list of stats about your iPhone, including device stats, hardware information, disk space and usage, memory usage, and network access, along with every font currently installed on your device. It's a nice list to have, so you can see exactly what you have access to on a technical level.
UDID+ is a tool that does only a couple of things, but those things are very useful, well presented, and perfectly executed for anyone who needs access to technical specs for debugging apps currently in development or customizing the iPhone experience in a closed environment.
