A leaked HTC Endeavour ROM has been posted on XDA Developers and it not only confirms Sense 4.0 but also some of its rumored specs, like the 720p resolution screen. The build.prop file also contains references to the Tegra chipset, Dropbox integration, eight megapixel camera, 1.3-megapixel front-facer, WiFi a/b/g/n, Bluetooth 4.0 and the "Endeavor" name. The platform seems to be Android 4.0.3 Ice Cream Sandwich but if you're a techy person head over to the source link and check out the goodies yourself.
As far as the phone is concerned, we're waiting for HTC to unveil the device, together with some other phones and tablets at next week's MWC in Barcelona.
