Great Site. I'll Check into it.
Thanks

If I were releasing a program with a regististration scheme, would it be advisible to use the DeviceID in a similar way to a desktop app might use the a hard drive serial number? Is the DeviceID always obtainable using this article's code? (I've tested it on my device and it works, but I'm wondering whether it will work on other devices.)
