Infineon Chipset May Be Cause of IPhone 3G Issues

JagsLive sends along a CNet blog piece about a plausible theory to explain the iPhone 3G connection problems many users have experienced. Apple has not acknowledged any such problems. "Richard Windsor of Nomura published a research note... Tuesday singling out the iPhone 3G's chipset, made by Infineon, as the probable culprit for the reception problems we reported on Monday. The dropped calls, service interruptions, and abrupt network switches experienced by iPhone 3G users reminded Windsor of similar complaints five years ago, when 3G phones were first launched in Europe. 'We believe that these issues are typical of an immature chipset and radio protocol stack where we are almost certain that Infineon is the 3G supplier,' Windsor wrote. 'This is not surprising as the Infineon 3G chipset solution has never really been tested in the hands of users. Some people will not experience these problems as it is only in areas where the radio signal weakens that the immaturity of the stack really shows.'"

No.

Crap testing is the cause of iPhone 3G issues. There are always issues before a product is released. The testing is supposed to find them. Something as obvious as this issue indicates that Apple didn't give a shit about testing.

I worked for Apple in Cupertino during the Apple ][ / Apple /// days. The transition happened then.

Woz was a genuine engineer, and in his spec all Apple ]['s were burned in over 4 days in a hot room (50 degrees C) before they were packaged and shipped to the stores. The ]['s were very well known for reliability, which along with excellent packaging (yep, not all Jobs' competence is Reality Distortion Field) very few were returned for any sort of quality issue.

The Apple /// was a slightly different issue -- there was a problem with a clock chip supplier that worked as an object lesson that you can outsource a lot of things, but responsibilty (if not actual testing) can't be one of them.

And due to pressures of IBM's release of the flawed but powerfully marketed brand-new 8086 based PCat that point, the first real competition in the business world put pressures on Apple that it hadn't encountered before, thus a decision to release what they had in bulk to gain market share and risk returns overrode the impulse to limit supply by running them through that hot room first. This was the first disjunct and marketing lesson (see Apple and "Black Friday" and "duck quack synthesizer" if you can find the reference) for a company that was learning about how to go from company to corporation in one huge lump. Apple grew from $0.5M to $0.5B in gross sales that year, in their defense, and that's a huge amount of change to absorb.

Money wasn't really a problem, learning to land the fish was.

Imagine -- if you have a job that moves dirt 1/2 ton at a time, you're fine buying a half-ton pickup to move it. You can even scale that up a few times. But if you're suddenly faced with moving a million tons of dirt, you have to find a more complex solution than simply buying a half-million trucks. Everything Apple suffered during that phase was a result of the huge success of the Apple ][. That kind of scale didn't bother IBM, but we had trouble finding places to put people and other concerns of gearing up.

It's an AT&T Network problem. Fido was similar

Looking at the thread on the Apple discussion boards, this seems to be an issue with the popularity of the new 3G phone and the inability of the AT&T 3G network to be able to handle the extra data load with such an internet enabled device.

I experienced a similar issue for a few days in Canada with the Fido and others with the Rogers 3G networks shortly after the July 11th launch. Within a few days, the problems mostly went away where I live and now I get great reception even at work.

There may be a few faulty 3G iPhones but this is mostly caused by a combination of faulty AT&T sims and problems with their network stability and capacity.
