Nokia has become the latest manufacturer \u2013 after Samsung and Motorola - to run an advert that mocks the iPhone 5, this time having a dig at its lack of colour.The Nokia Lumia 920 is just around the corner, and while the Finnish manufacturer's hero device packs a tonne of features, including the new Windows Phone 8 operating system, it\u2019s the fact that it comes in a range of colours that should persuade consumers to put down their iPhones.The 55-second advert shows a stream of customers all dressed in grey plodding along to a shop where they hand over their hard cash for a device labelled \u201c5\u201d. That\u2019s until one customer cheekily requests something in colour. Cue a change in tempo and various far hipper characters appearing.When the Nokia Lumia 920 arrives next month \u2013 sadly there\u2019s no UK date or carrier announced yet, only that it will be available from AT&T in the US - it will come in a striking yellow, bright red and more run-of-the-mill white, grey and black. The iPhone, in contrast, has only ever been available in white or black with the odd strip of metal.Nokia is clearly placing a lot of emphasis on the Lumia 920\u2019s appearance. Whether this in itself is enough to persuade customers to take a punt on the Lumia 920, we\u2019ll have to wait and see.Thankfully there\u2019s enough going on under the bonnet as well for it not to be dismissed as just a pretty face.
