Earlier this morning, we told you about HTC’s EVO 4G Shift (although this morning it was called the EVO Shift 4G) making a cameo in a RadioShack flyer, and this afternoon it looks like accessories for the device have made their way to Best Buy as well. Engadget was sent in images of the Invisible Shield screen protector, designed specifically for the 4G Shift’s 3.6-inch window, that arrived at a Best Buy retail location. Between this, the RadioShack advert, and CES being next week… the writing seems to be on the wall. Who’s interested in a EVO 4G Shift?
