HTC Eternity pics, a Windows Phone Mango with a 4.7-inch screen

German blog HTCInside (if you didn’t pick that up from the picture) has published the first supposed specs and pictures of a massive new Windows Phone from HTC. Named the HTC Eternity, the new device will be one of the first to run Windows Phone Mango, the promising next version of Windows Phone 7, which will have turn-by-turn navigation and a host of other needed and desired new features. More interesting than its ties to Mango, the new phone will have a massive 4.7-inch screen, almost as large as Acer’s monster phone and bigger than the 4.5-inch Samsung Infuse 4G. The phone may end up being too large for some users, though we’re excited that HTC keeps pushing it to the limit.

According to the brief stats sheet, the new phone is CDMA and GSM compatible, so it could hit AT&T, Verizon, or T-Mobile, though we’d lean toward T-Mob and AT&T because it lacks 4G LTE capabilities, which is fast becoming a requirement on Verizon’s network.

More specs:

Processor: 1.5GHz single-core from QualcommCameras: 8MP rear with LED flash and 720p video capture, and 1.3MP frontInternal storage: 16GBRAM: 512MBScreen: Super WVGA (800×480) Super LCD

One problem we had with the 4.5-inch Samsung Infuse, and something to think about here, is whether a WVGA screen will look good on such a large phone. Smaller 4.3-inch phones are coming out with 960×540 pixel screens these days. Hopefully the Eternity looks good next to one of these devices.

We have no word on when it will ship, but it will be one of the first Windows Phone Mango devices, so likely somewhere between September and November.
