The folks over at the FCC have just gotten an eyeful of the HTC PD15100 PDA phone, where said device will support GSM 850/1900 and WCDMA band IV, suggesting a T-Mobile debut should it ever be released in this part of the world. Apart from that, the PD15100 seems to be pretty advanced in terms of hardware, sporting both front and rear facing cameras, dual-band Wireless N Wi-Fi connectivity and wireless hotspot capabilities. Strangely though, it is nowhere near any leaked HTC device’s specifications, but we can’t rule out the possibility of this being one Windows Phone 7-powered smartphone by HTC. What do you think?
