Today RIM officially announced the BlackBerry Curve 9320. Straight off the mark T-Mobile UK and Three UK have both announced through their respective Twitter accounts that the latest Curve model is available on their network. T-Mobile UK, usually a network that releases BlackBerry smartphones a lot later than other UK networks, had previously outed the Curve 9320 by showing that it was coming soon to the network before RIM even made an official announce of the device.
T-Mobile UK already has the BlackBerry Curve 9320 available to purchase through their website. You can get it for free from £15.50 per month on a 24 month contract. Three UK on the other hand lets you get your mitts on it for £140 on pay as you go, although it is yet to appear on their website.
The BlackBerry Curve 9320 comes preloaded with BlackBerry 7.1, has a 3.2 megapixel camera and an FM Radio, to name a few of its features. Don't forget it also brings back the left convenience key in the form of a dedicated BBM key, though it does seem like this is configurable to launch any application you want. Three UK gives a video sneak peak which you can watch above.
