Unconfirmed rumours obtained from Pocketnow and a DLNA certificate for the device indicate that the upcoming HTC Kingdom is likely to be sold by Sprint as the HTC Hero 4G. Apparently, there are also indications of the device appearing in the EXIF data on photo-sharing sites.
We came across the HTC Kingdom in early May when a ROM of the device was leaked by the Chinese blog 911sniper. At the time not much was known about the device save for its qHD (540x960px) screen. Later Pocketnow released some updated specs indicating that the HTC Kingdom had a 1.2GHz Qualcomm MSM7630 processor, 768MB RAM, a 5MP camera with 720p video recording, and the device would launch with Android 2.3.3.
The rumours suggest that the HTC Kingdom will be launched by Sprint as the HTC Hero 4G, the carrier to originally launch the 528MHz, 3.2-inch HTC Hero, running one of the earliest Android builds (1.5 Cupcake). The Hero 4G has already passed FCC certification so it is likely we will be seeing the device sooner rather than later.
