(Pocket-lint) - BlackBerry 10 might have just been announced, but that doesn't mean Research In Motion has forgotten about current BlackBerry users announcing that BB 7.1 is now available for customers in the UK.

The update is available for the BlackBerry Bold 9900, BlackBerry Torch 9810 and 9860, BlackBerry Curve 9360 and 9380 smartphones, and the BlackBerry Porsche Design P'9981 smartphone from BlackBerry.

Starting today, customers can upgrade their smartphones to BlackBerry 7.1 free of charge over the air or using BlackBerry Desktop Software, the company says.

The new update adds BlackBerry Tag, a new way to share content with other BlackBerry customers using NFC technology and a battery saving mode to make your BB battery last even longer, and turn your phone into a Wi-Fi hotspot for five other devices.
