A few weeks ago Apple promised to re-jig the signal display bars on the iPhone by making the first three bars visually taller. Well, here's what they look like.
Gizmodo have superimposed the old bars over the new bars in the beta iOS 4.1 and here are the results:
As you can probably guess, this doesn't in any way improve signal, it's purely a visual tweak that makes bar 1 as big as bar 2 used to be.
Oh, and the obligatory XKCD cartoon.
Ugh ... this is what happens when engineers give in to designers.
