The problem did and still does exist. I am an all Apple family. 2 new iPads, one iPad 2, one MAc Pro, 1 iPhone 4S, 1 iPhone 4, one iPhone 3Gs, a gazillion iPod touches and iPod nanos.
Out of all these products, I only have problems with two. The iPhone 4 and the Mac Pro. Everything with the MAc Pro is resolved by changing some setting in the control panel. But the iPhone 4, well, indoors at work I get 2-3 bars signal. I ALWAYS drop calls if I hold it in the magic spot. This is hard not to do if you hold the phone with your left hand. This impacts 3G data also. I cannot check an app that needs to update if I cover the magic spot. Nevertheless, given how little the device is actually used a s a phone in such situations it is not a problem for me. But if you lived in an area where normal coverage sis poor then you have a major issue.
