| Sis files are specifically made for Symbian OS phones. Sis programs can access more of the phone's hardware like controlling the camera, turning on/off the infra-red, utilising realtime 3D graphics etc.
Jad and jar files are for java only. Java does not allow the phone to control anything else other than itself. For games and applications only.
Its like asking to dismantle a V12 Ferrari and putting parts into a goldfish to achieve the same speeds. |
