Hah, a bunch of us went to hear Cory Doctorow speak yesterday, and just a few hours later I realized that I'd wasted more than a few hours of my spare time dealing with some of the very issues he "is all about."
Turns out that my cell service provider was not allowing access to JSR-82 functionality by midlet .jars not signed by them. After debranding the phone, I am a happy camper. Gee, now I can do what I want without purchasing service from my provider!
BTW, there was yet another "Willi moment" when my esteemed colleague Jim M. pointed out that that I was pressing the wrong key during the wipe. Doh! Thanks, Jim.
