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.'"
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 have no idea what connection issues they are tal
I knew i shouldve waited.
Again bitten by Jobs's first-out-the-door gizmo.
I was also the proud owner of a tibook 400... yeah, the one that spontaneusly broke appart from heat due to the "TI" part (although it did look cool at first).
I guess some of us will never learn.
NO SIG
Can this be fixed by a firmware update? It said something about the stack which made me think firmware, or is it just shoddy hardware?
I guess some of us will never learn.
Not your fault, it's genetic.

...and what qualifications does he possess to comment on the possible cause of the alleged iPhone reception issues?
Seriously. This story is being widely distributed, but I have yet to see anyone ask about his credentials. Is he an electrical engineer with expertise in the design of cellular technology?
As far as I can tell, he's some financial analyst. So why would anyone consider him a credible source? Since when are the speculations of a financial analyst regarding the rather esoteric realm of RF engineering considered valid.
Am I missing something? Does someone know about his background?
battery life? As far as I know the iPhone pretty much beats all other 3G phones on battery life (whoops, scratch that. 3 Blackberrys beat the iPhone by a couple minutes.)
can you iPhone people just ATH and drive?
Fascism trolls keeping me up every night. When I starts a preachin', he HITS ME WITH HIS REICH!
I have noticed a lot more dropped calls on the iPhone 3g. Between the poorer battery life, the dropped calls, and the inability to unlock the sim, the upgrade feels like a downgrade from my old iPhone.

Good. I hope Infineon goes friking bankrupt and dies.
They are one of the manufacturers of Trusted Platform Modules.
That puts them right near the top of my shit-list.

I've been getting better reception on my 3G iPhone than I had on my Razr (also 3g)
Battery life is pretty crappy, have to recharge it every night. But that's all I need. I think that has more to do with the big honking screen than any chipset issue.
I have noticed that the signal indicator likes to sit at around 1 bar, but it's a bit deceptive because it works fine for a while (feels like empty on a car... still goes for a while anyways)
I know an anecdote isn't true for everyone... maybe he's in a bad signal area? Maybe he has a defective phone? I haven't seen what he's talking about.
I have developed a truly marvelous proof of this comment, which this signature is too narrow to contain.
AT&T has the best network around - More bars in more places. So this flaw should never be visible to the end user...unless AT&T has been lying to me.
Grump
Is it true that more people vote for the winner of American Idol, than vote for the president? -Ali G.
I have always been somewhat concerned about phone radiation, but so far, not enough to stop using them.
Hee hee hee..."I've always been a little concerned, not enough to actually read about the issue and decide if it's bullshit or not, I mean, it's only brain cancer, but anyway I just keep using them."
If only all of us could skip through life with such merry apathy.
I've had tons of connection/signal and dropped call problems ever since I upgraded my old non-3G iPhone to the 2.0 OS. I think this is a software problem.
The iPhone has a larger capacity battery than many of those models. There's also not one single Nokia model on that list, and the N95 outlasts the iPhone easily.

I think you're overestimating the size of the Apple fanboy market. That crowd certainly exists, but you're going to have a hard time convincing me that everyone who's got an iPhone got it just because it has an Apple logo on the back. That crowd was tapped out in the first couple weeks or so. The iPhone must be offering something to people that's making so many of them spend money on it.
But I'm sorry to interrupt. Please continue telling us all the details of your phone contract so we can fully comprehend how much smarter you are than everyone else.
One time I threw a brick at a duck.
It's because Batman installed his tracking transmitters in every cell phone in the world. That's why reception is spotty.. duh!
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.
Jesus was a compassionate social conservative who called individuals to sin no more.
I work in the industry. I know AT&Ts' 3G network is new and really unproven. 2G service is way more reliable. I have a BlackJack and when I have it set to 2G I have awesome coverage with no problems. With my blackjack on 3G I get dropped calls. Jerky sounding calls. All with full signal all over town. I've tried other 3G phones with same results. I think this is common for any new network that hasn't worked out all its blemishes.
This is not an iPhone chip issue. It is a network issue.
Living in same spot 10 years, always spotty reception on att ( also had for 10 years, first att, then cingular, then bellsouth, then att) and always spotty reception.
My last 3 Sony-Ericksons had the same bad reception, but at least I was ALWAYS able to make calls, staticy, but i cold make and receive them. Had maybe 5 -10 dropped calls ever. ALWAYS able to make calls whenever, wherever.
Now fast forward to the present iphone 3g and I go sometimes 5 minutes with that frackin Call Failed.... crap. Already had at least 20 dropped calls.
I want to throw the iphone through the iwall.
But I wont cuz the internet and stuff is like so cool on it, so I will put up with it. Just like every other person who is experiencing this drop call issue.
NO ONE will return the iphone to go back to their blackberry or whatever.
OVERALL the best personal tech experience I have EVER had and I know a lot of other peeps who feel the same way. ( and REAL peeps, not internet chat room forum, wow clan peeps. real flesh and blood peeps.)
In order of level of accuracy we have:
He may not be an expert in the field. Statistically, pulling a name at random out of the phonebook still has a greater chance of finding the right person than a company denying that there's even a phonebook.
The reality is that a large number of people are having problems with dropped calls, a very large number have significant problems with response time (particularly, it seems, if they've largely filled the device), and almost everyone are having problems with the device locking up and needing semi-regular hard reboots. Even first gen iPhone users who've upgraded to the 2.0 software are complaining about many more issues but at least they can revert - something not open to 3G users.
My guess, and I'm just a programmer/nerd and not a qualified phone engineer, is that it's a combination of newly sourced and poorly tested parts running in a major OS recode that also didn't get the level of testing any other wider ranging OS would get (they couldn't run a beta because Apple have a bitch of a time with leaks and cling on more tightly to avoiding them than most companies).
I may be right, I may be wrong. Statistically, whether the cat is dead or alive in the box, guessing about its state will sometimes be right. Apple's policy of keeping quiet and pretending there's no cat, no box and quantum states only happen to other companies ensures their answers are worse than other people's guesses.
