All the headlines will no doubt be about the Nokia Lumia 800, but the support act, the Nokia Lumia 710, is worth a look, especially if price is an issue and you have a nostalgia for changing phone covers.Yes, this is the second of the Nokia Windows Phones, the one pitched as the Nokia Sabre originally, but now under the Lumia umbrella. It offers many of the features, but to a lesser extent, if that makes sense. So 8GB of storage (compared to 16GB on the 800), a 3.7-inch WVGA ClearBlack screen and a five-megapixel auto-focus camera, although there is a 1.4GHz processor here too (with hardware acceleration and graphics processor). It doesn't quite have the sleek looks either, bit it does have interchangeable covers, which you can change to 'suit your mood'. An interesting retro twist there from Nokia.However, it does offer much the same it terms of the inner workings. Windows Phone 7.5 (Mango) is here as you would espect, as are the other optimised Nokia features from the Lumia 800, like Nokia Drive turn-by-turn navigation, Nokia Music and Mix Radio, for some themed music streaming. There's is also one-touch social networking via Twitter, Facebook and LinkedIn, threaded conversations (chat and SMS), easy sharing of photos, persionalised home screens.So if you can deal with the design shortcomings (compared to the Lumia 800) and some of the edges shaved off the features, the Lumia 710 is certainly worth considering. At least it is when it lands in the UK. This one, unlike the Lumia 800, isn't coming to the UK anytime soon. It's looking like a 2012 launch, which is a shame really – a lower-priced Windows Phone could really have been a contender in the Christmas run-up. When it does finally appear, expect a SIM-free model to cost €270. There's a choice of black and white with black, white, cyan, fuchsia and yellow back covers also available.
