What is the best way to develop my application so that it works on both 4.1 and 4.2 OS's. Should I be using the 4.1 or the 4.2 JDE? DO I need both?
I'm currently using the 4.1 JDE and the 4.2 Simulator (for the pearl) but my app isn't working on the simulator and I can't seem to get any good debug info from it.
