It got a grand launch back in September, but the Android-based HTC Desire Z hasn't exactly made a dash to market. Well, it's now on its way, hoping to 'wow' some businessmen as it goes.According to Cnet, the smartphone with the hinged keyboard has been spotted in a print advertisement from Vodafone, being sold on a business tariff rather than to the mass market. Which perhaps gives a clue where this handset is being pitched.Vodafone isn't selling it from its own site yet, but other agents are selling it on their behalf. For £30 per month, you can secure one with a monthly allowance of 3,000 minutes to UK landlines, 750 minutes to UK mobiles, 250 texts and 500MB of mobile internet. At the other end of the spectrum, an unlocked version sells for £420. Mobiles.co.uk is doing the business with it.For that money, you get that Android 2.2 operating system and its Flash goodness, as well as a 5-megapixel camera, a 3.7-inch touchscreen and a full QWERTY keyboard on a swwivelling hinge. The phone is in stock at the retailer now. Fancy seeing a hands-on? There's one here.
