iPhone 4: Lettera da Apple 
From Apple - Press Info
Riporto l'articolo in versione integrale... vorrei sottolineare la serietà del lavoro di queste persone ( alla faccia di fix, bug, service pack e quant'altro di zozzo ci troviamo dentro ad un PC senza accorgecene )...dell'onesta con la quale si ammette i proprio errori per rendere il prodotto ancora migliore. D'altronde, sbagliando s'impara no?! :)
Cari Utenti iPhone 4,
iPhone 4 è stato il lancio di prodotto most successful in the history of Apple. It was considered by critics worldwide as the best smartphone ever, and users have told us that love him. So we were surprised to read reports of reception problems, and we immediately started to investigate. Here's what we have learned.
For a start, picking up almost every phone in a way reduces the receipt of one or more notches. This is true for 4 iPhone, iPhone 3G, as well as many mobile Droid, Nokia and RIM. But some users have reported that the iPhone may fall 4 of 4 or 5 bars when required to cover the black stripe at the bottom to the left of the metal band. This is a much bigger decline than normal, and consequently some people have accused iPhone 4 you have an antenna designed in a defective.
At the same time, we continue to read articles and get hundreds of emails from people who say that the reception of the iPhone 4 is better than that of the iPhone 3G and I'm happy. This corresponds to our experience and our test. What can explain this?
We have discovered the cause of this dramatic decline of the notches, and is simple and surprising.
After some investigation, we were amazed to discover that the formula we use to calculate the bars that indicate signal strength display is completely wrong. Our formula, in many cases, incorrectly displays in more than two notches due to a given signal strength. For example, we see 4 bars when you should see two bars. When users observe a fall several notches when they grab their iPhone in a certain way, it is more likely to be in an area with weak signal, but they do not know why we are mistakenly viewing 4 or 5 bars. The sharp drop in marks is due to the fact that their number is not high never been true from the beginning.
To resolve this problem, we are adopting the formula that AT & T has recently recommended to calculate the number of bars to display for a given signal strength. The real power of the signal remains the same, but the bars of the iPhone will be displayed more accurately, giving users a better indication of the reception are available in a given area. We are also making the notches 1, 2 and 3 higher to make them more visible.
released a free update of software in a few weeks, which incorporates the correct formula. Because the issue is the original iPhone, this software update will be available for the iPhone 3G and iPhone 3G.
We returned to our laboratories and we retested everything, and the results are the same, the performance of wireless iPhone 4 are the best we've ever provided. For the vast majority of users were not affected by this problem, this software update will only make the bar more accurate. For those who have had problems, we apologize for any anxiety that may have caused.
As a reminder, if you are not fully satisfied, you can return your iPhone free of any Apple Store or Apple Online Store within 30 days of purchase for a full refund.
We hope that as much as we love iPhone 4.
Thank you for your patience and support.
Apple
