Well after generate sis file I take it and get into the phone (3650) by infrared but then I want to install another version of my aplication and with different name even but it is the same as the first with some changes.The problem is that always install the first aplication I got into the phone. I can not make any test for my recent aplications. Well, I go to the manager menu in the phone and delete the aplication. But always stay 19 bytes in aplications like residual. What can I do? Have I to format the memory or is there another solution? Well, waiting for your responses. Many thanks in advenced.
