The main issue in this case is that the BlackBerry Torch 9800 is not included on the supported Mobile devices list. This means that even though you can try to download and install the SlingPlayer Mobile application, it might not work properly.

It seems that the capacity of the Sling Media's support will not comment on future products, releases, updates or anything else of actual interest in these technical support forums. You may consider adding a post to this thread (https://community.sling.com/message/15760#15760) which has already been open in the Enchancement Request forum. There, it will probably carry more weight to the developers for consideration of future updates, rather than being posted in these technical support forums.
