We recently got a look at what LG is reportedly calling the X3 smartphone, and now images of what could be the company's successor to the Optimus 3D have surfaced. According to details obtained by PocketNow, the new 3D phone — currently referred to as the CX2 — appears focused more on form factor than any substantive horsepower upgrades. It is said to feature a 1.2GHz dual-core processor, a minor bump from the 1GHz dual-core processor of the original Optimus 3D, with the same 8GB of storage and dual 5-megapixel cameras (the 4.3-inch WVGA display will match the original on specs, though LG is said to have swapped out the panel for a brighter model). The big difference comes in thickness: the new phone reportedly measures up at less than 0.39 inches, a noticeable drop from the 0.47 inches of the original. NFC and DLNA support are also said to be on board, though apparently the phone will be a Gingerbread device on launch. With spring named as a likely release window, we wouldn't be surprised to hear more about the new phone, along with the X3, next month at Mobile World Congress.
