Spot on Carniphage. It seems a few people on this forum didn't read that article past the pretty graph about how signal strength is mapped to bars. Folks, that wasn't the point of his article! He starts that section, 'Before we dive in ' Dive in to what? The actual data about signal loss when you bridge the antennas!
Sadly more people here are just rabid fanboys. Just go by the facts, love my macbook pro but they really screwed up this iphone version. And finding out they've been boosting signal levels in the UI is just sad.
