A recent FCC filing has given us a glimpse into an upcoming Windows Phone device from HTC headed for Sprint and it could be the previously rumoured HTC Tiara.
The unknown HTC Windows Phone device features the model number PO88100 with it suggesting that it may feature Windows Phone 8.1 codenamed Blue. The FCC application notes that the device will feature WiFi, LTE and Bluetooth 4.0 in addition to a removable rear cover. Speculation suggest that the device may be the HTC Tiara which is said to feature a 1.2GHz dual core processor, 1GB of RAM and more. The device may even feature an UltraPixel camera and more.
The upcoming device could be called the HTC Eight if their recent naming schemes are followed or it could continue along the old HTC 8 model names.
