Currently using an old Samsung Omnia i910, rooted and running WinMo 6.5 custom ROM. Unfortunately, you cannot hear the ringer anymore and I've kind of given up trying to figure out why now that the LTE devices are about.
Still haven't decided on whether it will be the Thunderbolt or the Charge. Saw the latter today at a Verizon Store and that screen is AMAZING!! Also shot some video and still shots with it, and was pleasantly happy with those as well.
Will probably decide shortly.
