July 2, 2010 Letter from Apple Regarding iPhone 4 Dear iPhone 4 Users, The iPhone 4 has been the most successful product launch in Apple’s history. It has been judged by reviewers around the world to be the best smartphone ever, and users have told us that they love it. So we were surprised when we read reports of reception problems, and we immediately began investigating them. Here is what we have learned. To start with, gripping almost any mobile phone in certain ways will reduce its reception by 1 or more bars. This is true of iPhone 4, iPhone 3GS, as well as many Droid, Nokia and RIM phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way which covers the black strip in the lower left corner of the metal band. This is a far bigger drop than normal, and as a result some have accused the iPhone 4 of having a faulty antenna design. At the same time, we continue to read articles and receive hundreds of emails from users saying that iPhone 4 reception is better than the iPhone 3GS. They are delighted. This matches our own experience and testing. What can explain all of this? We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising. Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don’t know it because we are erroneously displaying 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place. To fix this, we are adopting AT&T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area' We are also making bars 1, 2 and 3 a bit taller so they will be easier to see. . We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G. We have gone back to our labs and retested everything, and the results are the same— the iPhone 4’s wireless performance is the best we have ever shipped. For the vast majority of users who have not been troubled by this issue, this software update will only make your bars more accurate. For those who have had concerns, we apologize for any anxiety we may have caused. As a reminder, if you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of purchase for a full refund. We hope you love the iPhone 4 as much as we do. Thank you for your patience and support.

Apple is insulting the public with this statement. Only the iSheep will be stupid enough to believe that it's all a software issue. Why don't they just recalibrate the damn thing to show no bars all the time. Then just think how amazing the phone will become? "I can make crystal clear calls on my iPhone even when it has NO BARS!!" And how fortuitously, this "update" will be released once all the early adopters are past their 30 day return window!
Sad. Software patches and spin aren't going to solve a harware problem. But then spin and software is what Apple does best, so I guess it's what they reach for first. And I guess they don't want to face the idea of recalling 1.7 Million phones. Hmm.. looks like it's time to kick back with some popcorn and see how this one plays out opcorn:
The number of iSheep that continue to believe and defend and try to prove that "every phone" has the same problem, is amazing. I marvel at how powerful Apple's marketing is that it makes seemingly sensible people refuse to accept that Apple can do something wrong, and at the same time quickly believe anythng and everything negative published about other manufacturers. Here is Mickey's take:
Great! Now my iPhone4 will go from 2 bars to No Service instead of 4 bars to No Service when I hold it. Meanwhile the 3GS next to it will be recalibrated to 2 bars, and stay at 2 bars while I hold it. Then I'll be able to complain about crappy AT&T 2 bar coverage AND about how bad the iPhone 4 antenna issue is!
Lol, if you return your iPhone 4, then all you would have to do is complain about the "crappy AT&T 2 bar coverage" RR, Just for you, from the macrumors forum:
Apples signal bar "patch" is smoke and mirrors to make you look away from the real hardware problem. If you look at RSSI (signal strength in dBm) you should see the same thing regardless of "patch" or no "patch" ...seems Apple is really angering even their most loyal customers. Not good for biz. A part of me has pity for them for making such a glaring antenna mistake, and another part of me is rolling on the floor laughing because they made such a glaring antenna mistake. C'mon, a first year RF student can tell you if you touch the antenna's dipoles you change their properties. I knew Apple wasn't good at RF, but had no idea they were that bad ...speaking of a good laugh, this really cracked me up :lmao: ..."Get a case?! Hans, this is why you're broke every week!" :lmao: [ame=http://www.youtube.com/watch?v=3h3Ogt2L44Q]YouTube - Hitler Reacts to the iPhone 4 Antenna Issues[/ame]
So if you look at it, Apple can push the blame over to AT&T for poor signal strength rather than a problem with the design after the software patch. Funny thing is AT&T is giving them the proper formula to calculate the strength. Now iPhone users will have proof of poor signal strength. :biggrin:
... Is Apple taking a page from the BP and Toyota handbook? Of course they're damned if they do and damned if they don't. Not an enviable position to be in... It will be interesting to see how this all plays out in the long run.
I believe Apple/AT&T is now waiving the 10% re stocking fee. It is a step in the right direction imho, finally taking some responsibility and not blaming the network or the users (for holding it improperly). BlackBerry9700/5.0.0.680 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/102
Actually, Toyota now says they never actually had a "sticking gas pedal" problem, it just turns out that they mis-calibrated the speedometer. They re-calibrated it now to show "0 mph" when the gas pedal is pressed to the floor, and the problem is solved They indeed did.

Apple is still not acknowledging any hardware issue; it will be interesting to see how many people are satisfied after the software update. I am sure no one on this forum will be, we know better On a side issue, the iPhone did show more bars than other devices, for the same signal strength. Viewfly posted having 5 bars at -95 db in his micro cell thread. On most phones that I have had, a -95 would show 3 bars max. Just my 2 cents.

In addition to "Hitler's" reaction, which RR posted in this thread, blogger John Gruber posted this Translation From Apple’s Unique Dialect of PR-Speak to English. I thought it was funny, but then, I'm not offended by "swear words". If you are, you've been warned. SW
I loved it, as I did RR's Hitler. . From the blog is what I mentioned in my post just before yours. This strategy had worked very well for Apple prior to the iP4's antenna issue, most every iPhone owner fell for it. BlackBerry9700/5.0.0.680 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/102
For Apple to say they were unaware of the RSSI-to-bars mapping scale is complete BS, and I think everyone can smell that. I'm sure they were well aware that they were keeping the bars artificially high to give the "perception" of a better signal, Apple loves to control details, especially highly talked about and visible ones like signal bars. On the other hand, if Apple said they were unaware that some mundane RF parameters were set wrong, like power control (see first iPhone), handover parameters, etc, then I would definitely believe that
I feared sooner or later Apple would turn into their fiercest rival, Microsoft, and settle on their own little planet of perception by feigning ignorance, then blaming faulty calibration (or whatever the heck it is) for the i4 signal issues. If it weren't for the fact they still make great products, I'd start running the other way...
I wonder if Apple is going to make the new formula a part of the carrier profile data. After all, why would any other carrier want their signal strength calculated using AT&T-supplied formula?
I thought along those lines too at first "Why would Apple apply an AT&T parameter to a phone sold world-wide on many networks?". But then, signal bars are arbitrary and meaningless, so really it doesn't matter. Network operators are usually more concernerd with "real" issues, like parameters that would affect their network or call quality. On a side note, I think most phone makers should really reevaluate how RSSI is mapped to signal bars. Most phones I see already show "full bars" at around -90dBm, which is not really a "great" signal. You drop a call around -100 to -110dBm, and as you see you can lose -20dB walking from one room to another, so your -90 could become -110 very easily. I think "full bars" should only be at about -80 or so. Well, the scale is roughly from -110 (worst) to -40 (best) so scale the bars however.
The most glaring thing about this is that the majority of iPhone 4 buyers were users of the previous iterations of the iPhone. Presumably, they've been gripping those older iPhones in much the same manner. After all, we're creatures of habit. If they never noticed such a precipitous drop before, how can it just be attributed to the calculation of signal strength?
"AppleCare has confirmed what we already knew: The incoming software update won't fix the iPhone 4's transmission and reception problems. They acknowledged the antenna problem exists, offering the same solution as before: Buy a case or hold the iPhone differently. I was secretly hoping that the software update would magically fix the iPhone 4's antenna design problem, because I really wanted to buy what otherwise is an great gadget. Unfortunately, the cosmetic change to the bar display—which promises to show the actual signal strength—will not fix the transmission/reception problem that countless iPhone 4 users are experiencing."
