Boo

The program I wanted to write for my phone was simple: I wanted to be able to select which side of the street my car was parked on, and have it add alarms to the calendar reminding me to move my car for street cleaning on the appropriate days of the coming week.

It was easy! And it runs perfectly in the Nokia emulator, but when I tried running it on my actual phone...SecurityException!

And basically I'm screwed, as it seems T-Mobile locks everything down...no "third party" access to user data (such as the calendar) at all.

Of course, I'm not even a "third party," I'm the second party, the owner of the phone. How annoying.

Needless to say, my next telephone will run Lunix.

And my code I hereby release into the public domain:
