I've seen some posts on other sites that iPhone 4's manufactured at or after week 27 (based on serial number) are shipping with a "fixed" antenna. Are people with these newer phones imagining things? Anyone have a similar story? I thought all iPhones have the antenna thing?

Engadget is speculating that iphones manufactured after week 26 or 27 that Apple may be applying a coating to the antenna that fixes the issue, but this is pure specualation.
Both of mine are week 27. I guess my frustration on pre-order day was worth it. My units are smooth between antennae segments and no detectable reception issues.
