Re: How many devices affected?
Pretty much... if its an issue of power control, then 3G iPhone devices are pretty much either
a) Not having enough power to transmit / receive (no harm to others)
b) Using too much power to transmit/receive, effectively killing off many other connections. WCDMA (similar to CDMA) calls transmits/receives on the same frequency at the same time, using different code. Similar to many people speaking/listening at the same time, but different languages, but at similar volume levels. If power control was using too much power, it would be similar to having someone with a bullhorn speaking while others are speaking softly.

From what I've seen and read, it's affected the entire network. Right after the iphone 3g launch, there were complaints of degraded data performance in a lot of areas of the country, even areas where ATTM's 3g buildout is at its most robust.
Of course, it's very difficult to sort out whether this was attributable to the iphone's allegedly passing unusual/poorly modulated data requests to the network, or whether it was just a matter of the huge influx of users (device specifics aside) that just overtaxed the network. Many people seem to think that ATTM was not prepared for the massive increase on market demands due to so many 3g users coming online all at once, so even if the iPhone has unique issue there are still underlying issues of underprovisioning of the network that have contributed to some of the problems.
But from my observation of general attitudes among iPhone users, a lot of people have had suspicions that the phone's performance, particularly on UMTS, is suspect, and people have been looking for an explanation.
So when things like this come out there is a tendency to give them some credence. You have to recall that there have been other, more solidly attributed reports that the iPhone has some radio issues, there were some people who tested it on the European 2100 MHz 3g band said that its 3g RF performance was below standard to such a degree that it probably should not have been certified. |

said by andyross  :Any details if this glitch would affect ALL 3G devices, or only other iPhones? It would affect other devices indirectly. If there are too many defective iPhones in one area they would have the effect of a denial of service attack which would affect any 3G device nearby.
