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.
