As LG prepares to launch the Optimus 4X HD, they need to make sure that the phone can even make it into certain markets. In the US, that’s where the FCC comes in, and it’s no different with the 4X HD. The handset just passed through our fine Federal Communication Commission, bringing with it AT&T compatible 850/1900MHz 3G bands. This means the phone can be imported at will, whether or not any US carriers decide to offer the phone. Anyone interested in the Optimus 4X HD?
