If you are a google apptomarket, you will find a program that will edit apk for you. You enter the data of your certificate, and then you change the settings in apk as the version number, change the name of the application, change its size, icons and orientation. Then you pack it for the Android market. I have already used it and have not yet received any complaints. It is easy to use and free. What more could you want ... besides the iphone version of the inventor of the app, but I think Steve Jobs will hunt me for just thinking about such blasphemy, oh well.
