I have an application that I had worked on a few months back, one version was for the S60-3rd edition phone. It worked on the phones back then.
Fast forward to now, I modified this application by simply changing a few String variables in a source file to adapt it to a different property I'm working on, and all of the 3rd Edition Nokia S60 emulators are telling me the JAD and JAR files are 'Incompatible With This Phone'.
Any suggestions on things that destroy the compatibility? I learned the hard way back when I first started developing that MIDP and CLDC settings need to be just right (although that never broke the application in the emulators, just the actual phones).
