HTC’s Windows Phone 7 offerings have been slim pickings, and aside from the three devices unveiled when the OS launched last year (Trophy, HD7 and Mozart) the company has more or less concentrated on strengthening their Android lineup. So it came as a bit of a surprise to see Engadget handling two newly announced Mango equipped HTC devices – the Titan and Radar – being handled on their site. The HTC Titan definitely lived up to its name – it sports an absolutely huge 4.7-inch SLCD display, 1.5GHz processor, 512MB of RAM and 16GB of flash storage. The Radar meanwhile packs a smaller 3.8-inch screen, 1GHz processor and 8GB of storage and is probably aimed at the mid-market sensibilities. The crew at Engadget says that the new devices will be made available (in the States, we suppose) come October, while the rest of HTC’s Phone 7 lineup will be Mango-fied in September.
