When the phone launched back in October, a very loose launch date of 2012 was given for the Nokia Lumia 710 landing in the UK.According to Unwired View, the launch date of the cheaper Windows Phone 7.5 handset in the UK could be 6 January, if you believe the listings of online retailers. The retailer we're talking about is Digital Phone, which is taking expressions of interest for the phone. But crucially, it isn't taking orders and hasn't given a price. Which does throw some doubt into the mix.It wouldn't be a huge surprise to see it land in early 2012. It gives the (current) flagship Nokia Lumia 800 a good run at the initial sales (and indeed Christmas sales), as well as keeping momentum going for the Nokia/Microsoft partnership. It also bridges the gap before the heavily-rumoured Nokia 900 too, which is expected to land with the Tango upgrade of Windows.As for the Lumia 710, that's a slightly cheaper, slightly lower specification of the Nokia Windows Phone. Expect 8GB of storage (compared to 16GB on the Lumia 800), a 3.7-inch WVGA ClearBlack screen and a five-megapixel auto-focus camera, along with a 1.4GHz processor (with hardware acceleration and graphics processor) and interchangeable covers. The SIM-free price quoted at launch was €270, which is still the best guide to a retail price in the UK, although contract deals are certain to follow if it does launch early in 2012. When the date is confirmed, we'll let you know.
