I added the 4.2.0 jar and removed the 4.3.0 version. It compiles fine, but I still see no icon on the 4.2.0.69 Cingular 8100. I also downloaded 2 more simulators. The Cingular 8100 with 4.2.0.71 simulator has the same problem.
The Verizon 8130 with 4.3.0.97 simulator runs the application fine.

I'm going to try the 4.2.1 and 4.2.2 simulators to see if they also have the problem.
