As if the mobile phone scene wasn’t competitive enough, HTC’s HD2 looks like it will be debuting sometime next week on T-Mobile UK, making T-Mobile the first carrier to offer this high-end phone. There isn’t any mention of when the HD2 will be released in North America yet, but there are some rumblings that T-Mobile USA might be picking it up. In case you’ve forgotten, the phone will sport Windows Mobile 6.5 Pro, HTC Sense (the new TouchFLO UI), capacitive display (for multi-touch goodness), 7.2Mbps HSDPA, Wi-Fi b/g, Bluetooth 2.1, 448MB of RAM, 5-megapixel camera with auto-focus, microSD card support, GPS and a lovely 3.5mm headphone jack. We’ve been talking about an “iPhone killer” for so long now, could this be it?
