Infineon Chip May Be Causing iPhone Troubles

According to a research report from Nomura, complaints of dropped calls and unreliable Internet connections on the new iPhone 3G may be caused by faulty software on a chip made by Infineon. Nomura analyst Richard Windsor wrote in a research note that the problem likely involved the 3G cellular network communications chip: "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."

Although representatives for Apple and Infineon declined comment, BusinessWeek reported that Apple plans to fix the problem with a software update in the near future. At any rate, a spokesman for AT&T, the exclusive U.S. carrier for iPhone, said that it was working well on AT&T's network and that the carrier had received very few complaints: "This is not something that's high on our radar screen. It's not something we've had a lot of complaints about," said AT&T's Mark Siegel.

For those who own a iphone 3g, i hope that a firmware upgrade will fix this.

Why is it that responsible reporting is so hard to do anymore? While yes, this "could" be the problem, it is NOT confirmed. I see the phrases:

may be caused by...

We believe that these...

almost certain that Infineon...


The words "may be, believe, and almost certain" are not proof. Maybe it is the cause, but it's not proven. Don't make the headline read otherwise.

responsible reporting? didn't even know it existed, to my knowledge, it is all about ratings and attracting viewers/readers... So if something is a 'maybe' then it will be 'maybe, but regardless you will die' kind of thing.

Okay, sorry about the "sensationalist" headline; you guys are right, the level of doubt was too high.

Eh, better to know ahead just in case. No different from medication side effects really that "may" cause blah-di-blahblah, even if very very few may experience it.

"This is not something that's high on our radar screen. It's not something we've had a lot of complaints about,"

Well buddy, you had better get in on your radar screen in a hurry because as a result of all this hubbub, I am putting off switching my 3 (family plan) lines from VZW to AT&T until this is resolved. My VZW contract is up in 2 weeks and I had planned to make the switch then, but no longer.

If it's an 'immature radio protocol stack', than the chip isn't really to blame, is it?

The radio stack would be running on the main processor itself.

Until you can replace the freaking battery, I'll never by an iPhone. What sort of lame-ass design decision was that, batteries in a phone that the user can't replace?
#7.1 Grandaevus on 15 Aug 2008 - 05:49
It won't put me off, during my history of using mobile phones I've tended to change to a new phone waaaaay before any battery got close to being worn out. I recall buying 1 extra battery once about 10 years ago, before the days of NiMH batteries.

maybe they need to change the name of the chip to inferioron or something?

This obviously is an "Apple" issue, not an Infineon problem. Other companies use Infineon chips with any issues.

Apple really have no clue about phones and their trainee engineer's have made a poor choice when they set the parameters that the chip operates at. Now the engineers are "learning" about how a phone system works (by trail and error) and will release some new firmware with a better choice of parameters.

Good luck to all the early adopters. Shame Apple don't spend a bit more money paying for decent engineers who design the inner workings, rather than graphic artists who make it look pretty.
#10.1 MioTheGreat on 16 Aug 2008 - 02:51
Indeed. As I said: If it's an 'immature stack' problem, then the chip is fine. It's amazing how Apple's faults get spinned off like this.

You obviously don't have an iPhone and have never used one. And guess who is/does!!

Apple doesn't know how to make phones . . . just like they don't know how to make mp3 players and computers and software, etc.

Just acknowledge the fact that this device is excellent so far, it's still early to make a judgment call on any serious flaws, and that "time will tell."

Engineering . . . lol . . . do you even know what you're babbling about? Or do you just throw out terms like this in the hopes that some of your **** will stick to the wall??

I think the physical design on the phone itself is quite ugly -- your finger marks show up way too much and I'd love a slide out QWERTY keyboard, whether it be a 2touch or not. The Operating System on the iPhone is quite beautiful, and works extremely well especially in comparison to Windows Mobile 6. The entire interface works well with your fingers, whereas the WM environment is more suited to Stylus use still (Look at the Messaging app for what I mean). With that being said, clearly the media player on the iPhone is far superior to Windows Mobile (Windows Media Player), although the HTC one isn't too bad -- getting there.

All in all, as you said -- time will tell. It appears that each competitor is learning from each other in trying to create the ultimate device. I just can't stand the attitude of most Apple Fanboys, I personally love my HTC Touch Dual, it does absolutely everything I need it too and works great with my WinXP machine (not saying the iPhone wouldn't). But there's a reason there are competitors in the arena -- for choice and for the people to make up their mind, you pick your device and I'll pick mine -- no reason to hate though.

Microsoft / Windows MUST be behind this.

Best device I've ever owned.

Not one problem. People need to take care of their ****.
