I'm especially interested in the new features for the LG Optimus 3D and 3D Max. I own one of each.
The LG Optimus 3D Max (ie: the new one) is a huge step up from the Optimus 3D. It's faster, lighter and thinner and has double the RAM. It's like a Samsung Galaxy S II, but with 3D camera and glasses-free 4.3 " 3D display.
The phones are more than up to the job as they are, but the update to Anroid 4.0 will be nice to have anyway.
I got my LG Optimus 3D Max via Mobicity.co.nz.
