It's really annoying to find out what you cannot do with non-signed midlets. For example: 1. Your app cannot browse directories without the user being asked for permission on every change of directory. Try deveweloping a file browser with that restriction. 2. You cannot use a SocketConnection to connect to a remote host to port 8080 (only HttpConnection is allowed without beeing signed). Try developing an http-proxy with that restriction, when you want to forward every connection to another proxy on port 8080. And the Problem with being signed is that you have to have about 5 different certs on your key to be accepted on any phone by any manufacturer on any carrier. Those certificates are not free. They cost about 300$/year each. This was really annoying. I am so glad I do not have to do this on Android.
