Is it possible to send an .jad application from my computer to my 9000? i have tried it by going to media and reciving that way but saves someware I can't find. Any proper way of send application from a pc to Bold?
No. You can send the file, as you've done, but a .jad file will only work for OTA installation of an application, i.e., it has to be downloaded to your BB from a server to install the app, not simply transferred as a file.
You wouldn't even be able to install an app by simply transferring its .alx and .cod files to the BB, either -- you'd have to run App Loader.
