Consumer Reports CONFIRMS existence of hardware related antenna problem

Apple you need to bite the bullet and recall these phones otherwise you're going to suffer tarnished brand image. Don't make this another iMac yellow tint problem and own up to your problems. I'm not upgrading my phone until this issue is confirmed fixed. I'm a long time Apple customer but this is unacceptable.

A lab has verified hardware related antenna issues. Read more: http://blogs.consumerreports.org/electronics/2010/07/apple-iphone-4-antenna-issu e-iphone4-problems-dropped-calls-lab-test-confirmed-problem-issues-signal-streng th-att-network-gsm.html

If the restore of the JB'd 3GS onto the iPhone 4 allowed the dB meter to be displayed, it has modified the standard iPhone 4 software. Fact.

Also, do not make sweeping statements, I know exactly how software works, in fact I write a lot as part of my job.

Let's make it simple....

If under certain circumstances, the firmware was to report a signal lower than that actually received at the antenna, any component of the iPhone 4 (Phone, data transfer, displaying of signal bars or dB meter etc etc) which depends on that reported signal level would receive incorrect data. If the firmware doesn't know how to interpret the effect of bridging the antennas it may be catering for it incorrectly.

To those in denial.

If you read the article and watch the video, CR explains how they confirmed it is a hardware problem and clears up why they think the iPhone is a great phone with great features, but simply can't recommend it.

Yes the phone is pretty however some of us in the real world need to be able to use our phone for.. well... a phone.

Here is the article for those too lazy to google.

So, how long until this thread gets deleted by apple too?

Perhaps you would like another source.

The fact that this thread hasn't been killed yet, doesn't mean they haven't been deleting threads. Perhaps they stopped because they got called out on it. Is there no limit to the blind followings of the Apple Fanboys. You make good sheep. Don't be afraid to think for yourself.

If the antenna "problem" ultimately reduces to a user's hand establishing a relatively low-resistance bridge between the antenna elements, Apple can perhaps substantially mitigate the problem by fixing a transparent, non-conductive appliqué over the antenna ring gap. (Like a piece of Scotch tape, but obviously a little more robust.) The appliqué could be incorporated into the manufacturing process, and would be more attractive and commercially-viable than mandating the purchase of "bumper" rings for every iPhone 4.

Of course, if the coupling problem is more involved--i.e., it's not just simple bridging of the gap--then my solution won't cut it.

Interesting read. I would point out as well however the person writing the article has clearly not watched the testing video as that is where some of the items he is questioning are stated. (like the 20dB drop) This makes me question the thoroughness of his response. I'm not outright discounting it, like you I prefer proof... but when he missed something that blatant I question how much he researched his reply.

I simply don't buy the explanation provided by Apple. If this is truly a software glitch, whereby more bars are shown than are actually present, then why would this vulnerability ONLY manifest itself when you touch the antenna. Moreover, good to see Apple is hiring more of these frantically. Looks like they know they need to fix these, instead of "just don't hold it that way":

If you actually read the article, you would realize that all the author did was have the phone report what it detects as the signal strength. This was possible already in older ios versions. If apple can't even write software that properly reads signal strength, they have much bigger issues on their hands. Also, all 3 phones reported the same signal strength except when held at the bottom of the phone. Obvious the answer is that every phone can't report signal correctly. The obvious answer is that bridging the two antennas causes a signal degradation but you can't seem to admit that.

How is a conclusive proof different from a plain old ordinary proof?

There have been several tests published by different testers who all come up with the same measured signal degradation figures when the gap in the antenna band is bridged by skin. In addition to less rigorous tests that also show a signal degradation, but not as well quantified. Plus thousands of anecdotal reports of dropped calls and reduced bandwidth when that spot is touched. What would you consider a proof?
