Sprint customers holding out for the HTC Evo 3D can now inch slightly closer to that glasses-free display -- without dropping by RadioShack. The carrier has confirmed that you can reserve the WiMAX handset by visiting a Sprint-owned retail store and plunking down $50 for a gift card. There's still no word on when you'll be able to get the device in-hand (and the 3D's exclusive carrier is mum on pricing), but, if you don't mind reserving a phone without any hint as to how much you'll eventually need to pay, then Sprint seems happy enough to swap your Grant for a spot on the list.
