Apple has released the firmware promised to fix the signal bar issues with the new iPhone 4. To make this clear, the problem, for me, seems to be a hardware issue. When I hold the iPhone in any way that covers the gap between the two antennas, I lose signal strength. I’ve demoed this in the video below. Now, does the firmware fix the problem? Let’s find out! I’ve also recorded what happens when holding the iPhone in the same way on the new firmware, 4.0.1.
As you can see in the video, the problem has not been solved by a software update. Also, the new antenna bars are ugly…
Apple claims the update “Improves the formula to determine how many bars of signal strength to display” and is compatible with iPhone 3G, iPhone 3GS and iPhone 4.
The download is 579.3 MB for iOS 4.0.1 for iPhone 4.
