Research in Motion and Sprint are now delivering the BB OS 7.1 update to two devices: BlackBerry Bold 9930 and Torch 9850.
This update brings mobile hotspot functionality to these phones.
This update has been on its way to the owners of compatible devices for a couple of days now. It is now available from the Sprint website for direct installation on the phones.
The two companies have not spoken about any other feature update though we assume that there would be some bug fixes too.
