HTC's next flagship handset has been given its third name today, as more details emerge about the Taiwanese company's first quad-core smartphone. Initially called the HTC Edge, the device was renamed the HTC Endeavor earlier this month, but it's now being branded the HTC One.

Thanks to a leaked ROM that surfaced this week, we already know a lot about the One's internals. The handset is expected to feature a high-definition 720p display, an 8-megapixel rear-facing camera, and a 1.3-megapixel front-facing camera. However, arguably its most exciting features for Android fans are its 1.5GHz quad-core NVIDIA processor and the Ice Cream Sandwich operating system.

MoDaCo now has even more specifics on what is shaping up to be a spectacular smartphone. The site claims that the One will be thin, "without compromising HTC's renowned build quality." It also reveals that the device will not feature hardware buttons on the front as previously rumored, and that all of its keys will be on-screen — much like the Samsung Galaxy Nexus, the world's first Ice Cream Sandwich-powered smartphone.

Only the power button and the volume rocker will be physical. Also like the Galaxy Nexus is its 5-pogo-pin connector for a speaker dock, which is likely to be a Beats branded accessory, according to the report. While we're on the subject of Beats, the One will also be Beats branded and will come with a set of Beats headphones like those that began shipping with the HTC Sensation XE.

There will be no microSD card slot, according to MoDaCo, but there will be 32GB of internal storage as standard. Additionally, the handset will support mass storage mode, which isn't featured in stock Ice Cream Sandwich. Like the iPhone 4S and the Nokia Lumia 800, the HTC One will use a micro-SIM.

Now for the most exciting bit: The One's quad-core Tegra 3 processor had been confirmed as an NVIDIA AP33 1.5GHz XMM6260 chip, which will be accompanied by 1GB of RAM. It's safe to assume, then, that the device will not be a poor performer. It will also get a 4.7-inch Super LCD screen rather than the OLED display that was suggested in some reports.

As for software, the One will ship with Ice Cream Sandwich 4.0.3, with the HTC Sense 4.0 user interface.

While I may not be a fan of the Android operating system, I think the HTC One is going to be a terrific device if these reports are true. We're sure to get confirmation later this month from Mobile World Congress.

Are you excited for the HTC One?
