We just got a quick update from the OEM, the front frame you see on the right was made with a recently improved manufacturing process. What's the difference you ask? Well, the older process they used before has a chance to produce the "Rough & Bent" effect on the frame and made it not sit flush on the middle frame as shown below. But that's no more thanks to their revision on the way they manufacture them. I was told this was one of the reason why Apple didn't mass produce them yet. All new orders will have the new and improved front frame.
In addition, I was told that there are no signs that a hardware fix for the antenna issue is underway.
