ZTE isn’t your household manufacturer name but prepare to hear it a lot as they unveiled quite a large lineup at MWC. Most notable is their flagship ZTE Era. The Era joins the quad-core cool kids’ table by rocking NVIDIA’s Tegra 3 4-PLUS-1 processor. Interestingly enough, it also features NVIDIA’s Icera 450 HSPA+ modem. Other specs include:

One has to wonder if there will be any surprises at this year’s Mobile World Congress. Almost every OEM has already announced their devices, videos, images, etc., and now we’re seeing a leaked press shot of the HTC One X (aka Endeavor, Edge) which has apparently undergone some changes. This image paints quite a different picture from the one we saw last week as HTC seems to have dropped the four button lineup in favor of the three button ICS design.

LG is certainly looking to make the biggest splash this year at Mobile World Congress. They have been announcing device after device, and now, they’ve gone ahead and unveiled the cream of their crop — the LG Optimus 4X HD.

Well what do we have here? Could this be the next Motorola Atrix? This photo along with some rumored specs popped up on a few sites today and adds another quad-core smartphone into the pool of “we want now” devices.

The lack of buttons would mean we are looking at an Android 4.0 device and if rumored specs are to believed, an incredibly powerful one.

It started off as the HTC Edge, then it was the HTC Endeavor, and now it’s looking like it will be the HTC One X. Regardless of what name HTC eventually decides on, this is one beast of a phone that HTC fans are dying to get their hands on. Leaked specs have been floating around for a bit, but now, thanks to Paul O’Brien over at MoDaCo, we have a pretty good look at what the HTC One X will be packing.
