Apple offers solution to iPhone 4 reception problems

DIY solutions and fake emails

Apple maintains its lab testing shows the new iPhone's wireless performance is the best yet and the majority of users have been untroubled by reception issues.

However, a fan site claims it has solved the problem using rubber charity bracelets, instead of a $29 rubber case Apple has previously suggested could aid reception as well as protect the phone.

In a DIY project even Blue Peter would be proud of, the unofficial Apple weblog suggests users cut holes in a rubber charity bracelet (like Lance Armstrong's Livestrong bands) for the phone's headphone jack, silent switch and dock connector, thus insulating the metal antenna. 

The Livestrong foundation set up by cyclist Armstong told Business Week it had noticed a rise in its site traffic since the iPhone 4 solution came to light.  But unsurprisingly Apple suggests people should buy its official cases and avoid holding the phone on its left-hand corner

In a busy week, Apple has also confirmed emails apparently from Apple CEO Steve Jobs, insisting an iPhone 4 user should ‘calm down' over reception problems, are fake.

Mobile phone site Boy Genius Report published a conversation purportedly between Jobs and one of its readers.  In the exchange, the allegedly fake Jobs tried to placate angry ‘Tom' about his iPhone 4's reception problems.

Gems from the increasingly heated conversation in which ‘Tom' attacks Jobs' ‘jackass' comments, include replies from ‘Jobs' of: "No, you are getting all worked up over a few days of rumors.  Calm down," and "you may be working from bad data. Not your fault. Stay tuned. We are working on it."

Apple's press department reportedly strenuously denied these messages were sent by Jobs. 

In an intriguing twist to the iPhone ‘fakery', another site, AppleInsider insists it was offered what would appear to be the same email exchange for publication by a bloke in Virginia...for lots of cash, of course.

It says the man apparently posted a YouTube video of him blocking signal on an iPhone 4 and was swiftly contacted by Apple, resulting in the now well-publicised email, which he tried to sell to various members of the tech industry.

The site says it was contacted by a Jason Burford of a small advertising firm who tried to sell the email and offered to send headers for proof.  He admits to ‘kind of going off' at Jobs.

Do you like being fobbed off AGAIN by Apple? hahaha
I have heard it all now….
The formula of calculation and what looks to me like an obvious fiddle to make it appear that iPhones always have amazing signal by displaying 5 bars for a huge dB range are well discussed in Anandtech's review, posted earlier this week.
Funnily enough, there's not really any way to easily test their explanation. Possibly using Speedtest to compare internet speed in an area with 4 bars where the signal drops off to nothing, with an area with 4 bars where the signal doesn't drop off to nothing? It'd be kindof amusing to discover their ‘fix’ actually just lowers the reported signal of areas with mediocre signal by a couple of bars, rather than genuinely correcting a signal misrepresentation :D

Judging by Anandtech's data and their explanation I think that's exactly what they will do.

Before we dive in, let's talk about dynamic range for a second. For a while, I've talked about how iOS reports the quality metric with a compressed, optimistic dynamic range. On iOS, 4 bars begins at around -99 to -101 dBm. Three bars sits around -103 dBm, 2 bars extends down to -107 dBm, and 1 bar is -113 dBm. To give you perspective, for a UMTS “3G” plant, -51 dBm is the best reported signal you can get - it's quite literally standing next to, or under a block away from a tower. At the other extreme, -113 dBm is the worst possible signal you can have before disconnecting entirely. With a few exceptions, signal power as low as -107 dBm is actually perfectly fine for calls and data, and below that is where trouble usually starts. However, you can see just how little dynamic range iOS 4 has for reporting signal; over half of the range of possible signal levels in dBm (from -99 dBm to -51 dBm) is reported as 5 bars.

I'd guess they will just spread out the bar intervals a little more.
