The LG Optimus G Pro will run on the Android 4.1.2 Jelly Bean operating system, with pre-orders beginning from May 3 onwards. Of course, if you are one who wants to make a trade-in by ditching your old phone for this spanking new smartphone, then you can also be eligible for up to $100 off the new device, now how about that? Certainly this should be incentive enough to make that upgrade, no? With 32GB of internal memory and up to 64GB of expandable memory, you know for sure that the LG Optimus G Pro is going to be a killer mobile entertainment device.
