can any one tell me what the is mime type of .alx file ?
It seems it would be application/octet-stream from I personally would stick with this as a posed to application/xml because I wouldn't want browsers to render it but rather for the browser to simply download it and put it in a folder some where nice and tidy for the bb-tools to use.
That being said you do not download a .alx file to a blackberry you download it to your desktop and use it via the blackberry tools to install the application.
