Xda line of smartphones from a number of different sources over the years including HTC and ASUS -- but Pantech? We're pretty sure that's a new one. Then again, WinMo 6.1 dual sliders aren't exactly easy to come by, so we suppose O2 simply did what it had to do to get one in the lineup when the time came. If this so-called Xda Venn looks familiar, that's because it's just a Matrix Pro tweaked with O2's corporate branding, featuring the same 2 megapixel cam, GPS, and HSDPA as its North American cousin on AT&T. It's not on sale yet through O2's online shop, but the plumbing appears to be in place, so we're guessing it'll be available soon.
