HTC Eternity leaks: 4.7-inch 1.5GHz WP7.1 Mango superphone?

It's been a long time since we saw a new Windows Phone 7 device – barring Nokia's "Sea Ray" prototype – and so consider our interest piqued by the HTC Eternity, billed as a Windows Phone 7.1 Mango device that could well arrive in the early fall alongside the updated OS. HTC Inside scored the details, which tip a massive 4.7-inch WVGA Super LCD touchscreen, 8-megapixel main camera supporting 720p HD video recording, 1.3-megapixel front-facing camera and 1.5GHz processor.

That CPU is said to be Qualcomm's MSM8255, the speedier variant of the chip already found inside the HTC Sensation. Bizarrely, HTC is said to have paired it with a mere 512MB of RAM – along with 16GB of internal storage – which would be more than a little underwhelming. Other specs include HSPA+ with download speeds of 14.4Mbps and upload speeds of 5.76Mbps, network depending, along with WiFi b/g/n, Bluetooth 2.1+EDR and AGPS/GPS.

An FM radio, DLNA support, G-sensor, digital compass and dual microphones round things out, all in a handset said to measure 130.6 x 70.63 x 9.9mm and weigh under 170g. We've had out ruler and crayons out, and that would certainly be enough to accommodate a 3.7-inch panel, albeit making for a quite a handful of a device. Still, that hasn't dissuaded HTC before, the Desire HD being a good case in point (though the Eternity would be larger still).

Mango is tipped to bring with it front-facing camera support, among other things, though it was absent from the build we used for our technical preview. This could all be fake, but with Microsoft saying it has no plans to use Windows Phone on tablet hardware, an oversized pseudo-MID would be a welcome halfway house of sorts.
