The HTC Eternity has leaked. At first glance, it may look like most HTC handsets, but it's got one thing that we've never seen before: a monster 4.7-inch display, the biggest we've seen so far on a smartphone. The Super LCD screen has a WVGA resolution, according to the German website HTC Inside. I guess the name comes from the fact that the screen looks like it just goes on forever.

The biggest problem with having such a huge screen is of course battery life. The device apparently has a 1,650mAh battery inside, but we won't know how long that will last until HTC makes the device official. If it doesn't last at least the full day, we won't be able to say that it's worth the purchase.

The phone is clearly running the Windows Phone operating system. Judging by the front facing camera, the HTC Eternity will likely ship with Windows Phone 7.5 (codenamed Mango). This also means the device won't be out until this fall.

Beyond the screen and the OS, other specifications have also leaked. The HTC Eternity is powered by a single-core 1.5GHz processor, features an 8MP auto-focus camera with dual-LED flash supporting 720p HD recording, a 1.3-megapixel front-facing camera, and 16GB of internal storage. In terms of connectivity, it has the usual Wi-Fi, DLNA, GPS, and Bluetooth support.

The HTC Eternity's specifications easily beat what the current Windows phones offer, and this is to be expected with Windows Phone 7.5 coming out soon. Still, we want to see what else Nokia has up its sleeve (in addition to codename Sea Ray), not to mention Samsung, LG, Dell, Fujitsu, and ZTE.

This device tells us something else about the Windows Phone. It appears that upcoming Windows phones will be very unique from each other, which is great news for consumers.
