This whole launch of the iPhone 4 and it's signal reception issues has sounded eerily familiar ever since it popped. So I did some searching, and sure enough, the 3G launch was plagued with similar problems. Not exactly the same of course, but similar. The forums were abuzz with reports of low signal and dropped calls, some related to the phone being held. Update 2.0.1 addressed an issue with how the phone connected to cell towers, and 2.1 addressed an issue with signal bar display. General consensus was those who were showing 1-2 bars now showed 4-5 bars after the 2.1 update. Discussions talked about whether this was purely cosmetic, an actual signal boost, and whether the display was actually more accurate. Here's an example of an article the came out at the time: http://gizmodo.com/5050123/iphone-21-firmware-review-it-fixes-everything-we-can-see As far as I know, subsequent updates did not include any further changes to signal strength or signal bar display. This upcoming update is said to be for not only the iPhone 4' but for both 3G models. Does this mean Apple is actually saying that the 2.1 update all along was merely a cosmetic fix and it's been incorrectly reporting signal strength all along? It certainly appears that way, and the update will just reverse 2.1.
