Now, here is Apple contradicting itself; if the iPhone 4 problem is due to a glitch in the Math responsible for displaying antenna bars corresponding to the level of received signal (RSSI), why have they give out rubber cases to iPhone 4 customers?
Besides, I do not buy the idea of Apple consulting AT&T to determine the best formula for indicating how bars of signal strength are indicated on the iPhone 4g. This type of collaboration is anti-consumer - the air interfaces are standardized and Apple should just display what it measures of the air on its iPhone - AT&T should not be influencing this measurement.
Finally, if Apple maintains it's the Math, then consumers can verify this by testing out a different phone at the same locations the iPhone 4 experiences signal degradation.
An analysis was made of the iphone 4 antenna problem.
Clearly not a software problem. I've heard that very quietly Apple is exchanging customers iphone 4 with an improved "antenna" version. So, if yours is not working try to exchange it.
It will now be appreciated if Apple acknowledges the problem, takes its customers into confidence and takes them alon with the solution path it has planned to solve this problem. A feeback/replay to all of us by Aplle spokesperson is in order.
This antenna stuff all bodes unfavorably for Apple. Consumer Reports, which many consumer follow for smart buying decisions, is not recommending buying the iPhone4 until Apple fixes the "hardware" problem. It's not a matter of adjusting bars in software to suit clear reception.
This entire scenario suggests that Apple needs to review their testing and qualification process. Embedding the antenna in the chassis brilliant? It's hardly brilliant if it doesn't serve the functional purpose. Quality and reliability are really secondary in this market. We have an iPod graveyard upstairs which is testimony to that. I was pleasantly surprised recently when an iPod was replaced by Apple more than 2 years out of warranty because of a "manufacturing defect." As long as phones last to the next phone upgrade, we usually don't care...
The idea of embedded the antenna to the chassis is quite a brilliant idea; yet, whether it is engineering possible is still a question. I believe the situation will get better if Apple can stay quiet and focus on looking for a solution in addition to finding the root cause . Regardless of the current situation, iPhone 4 is still selling dozens. Bumper is going along with it (with a cost).
