Yesterday, Apple released iOS 4 update, which was one day before its press conference. The iOS 4.0.1 has obviously made the signal bar look taller. According to various media and blogs, the update is reportedly to have new software (new formula) to calculate the signal strength and to display it more accurately. Read here and here.

iPhone 3GS and iOS 4.0.1

The above screenshot shows the signal bar on my iPhone 3GS with iOS 4. By comparing with the screenshot below, it is obvious that the signal bar (especially bar 1 and 2) has become taller.

At the same location (my desk), I covered the back of my iPhone 3GS with my palm, the signal would drop 1 to 3 bars after about 22 seconds. After updating to iOS 4.0.1, I repeated the test. The signal bar would reduce 1 bar after more than 25 seconds.

Well, this is a very low tech test and is not accountable to conclude that the new software in iOS 4.0.1 has displayed the signal strength more accurately. Anyway, there is a huge difference before and after.
