The LG Optimus G Pro became official on Japanese carrier NTT Docomo last month, but we've yet to hear anything official about where else the phone might launch. Today brings a rather tantalizing leak, however, suggesting that the G Pro might be headed to LG's native South Korea with a refreshed spec sheet.
According to images obtained by PhoneArena -- one of a spec list, the other of the device itself -- it appears the Optimus G Pro could be headed to Korea with a 5.5-inch 1080p IPS-LCD display and a 3140mAh battery. That's up from a 5.0-inch screen and a 3000mAh battery in the Japanese version. Also listed is microSD card support up to 64GB. Other specs match Docomo's version directly -- there's a a 1.7GHz quad-core Snapdragon S4 Pro inside, along with 2GB of RAM and a 13MP rear camera. And Android 4.1 Jelly Bean is preloaded along with LG's custom UI.
Based on branding seen in the second image, it looks like the Optimus G Pro will launch on Korean carrier LG U+. We'll likely see the G Pro in person at Mobile World Congress at the end of the month, where we might also learn more about international availability.
