What's big, mostly white, and set for a Korean launch tomorrow? That's right, the LG Optimus Big! This 4.3-inch whopper, LG's largest handset to date, touts a 1GHz dual-core processor, a slightly skinned Android 2.2 as its OS, HDMI output, a 5 megapixel camera, and 16GB of built-in storage. That spec sheet sounds mighty close to the elder Optimus 2X that launched earlier in the year, though a couple of items have also been borrowed from the still unreleased Optimus Black. They are the NOVA display, which can crank all the way up to 700 nits of brightness, and WiFi Direct, which allows for wireless inter-device communication without the need for an intermediary WiFi access point. This big, delicious spec sandwich is hitting its home market on April 28th, but there's sadly no word on when and where else it might show up. Just keep an eye out for it, shouldn't be that hard to spot.
