RadioShack began taking pre-orders for Sprint’s HTC EVO 3D last week, and now the phone’s price tag may have been confirmed to be $200, or $500 off contract. An apparent leaked advertisement suggests that the device will also come with Green Hornet 3D pre-loaded, and it looks like anyone who trades in an HTC EVO 4G or HTC EVO Shift will be able to knock $100 off the purchase price. Unfortunately there still aren’t any details on a specific launch date, but if you want to get your EVO 3D with a hint of Seth Rogen, you may want to head over to your local RadioShack now.
