HTC EVO Shift 4G to arrive on Sprint in early January?

A new HTC phone has been rumored to be arriving on Sprint in early January 2011. The device sports the model number APA7373KT. At this point in time, nobody knows what the device is, but it’s been speculated to be the HTC Speedy/Knight/Evo Shift 4G- Sprint’s version of the Desire Z/G2/Merge. Android Central did a Google search and found a Russian version of the Desire Z, so it looks like that could be the one. Will it have 4G WiMAX support? It could even be a totally different phone. I guess we’ll just have to wait a few more weeks before we find out. What do you think the APA7373KT is?
