HTC launched itself back into Windows Phone support at its special event Thursday with two new models. Topping the group, the Titan (once codenamed the Eternity) is the biggest Windows Phone ever and has a 4.7-inch (albeit 480x800) touchscreen in a relatively slim 0.39-inch unibody frame. It confirms front camera support in the Mango update to the OS and has both a 1.3-megapixel front camera along with the rear eight-megapixel piece.
