BS. This is just immature firmware. Apple/Infineon needs to get their act together.

Meat?

Uh, he's an "analyst" with a securities brokerage who's only "almost certain" where the chip even comes from, let alone if there's a perceivable flaw.

Who is this guy and should his apparent gut feeling be afforded this much weight?

I mean, "issues are typical of an immature chipset and radio protocol stack" is a pretty darned broad swipe.

It is amazing that if this is the case that testing did not case this issue to show up. That is assuming that real world testing was done.

It is amazing how this years wonder TOY can become trash in only one month.

What makes you think that's the case? The article states specifically it's not firmware fixable and will require a chip replacement.

The article is wrong and it's PURE speculation. The Infineon chip is used in other phones as well and it's made to fall within the GSM/UMTS/HSDPA specifications. The problem is : fine tuning it to a particular situation/network. All this happens in firmware where certain parameters are being tweaked, perfected. Apple has a LOT of bread on their hands seeing that this is an ultra popular handset that is being sold in MANY different countries for many different networks.

An infineon chip or this infineon chip is used in other handsets?

I think its too early to say. Many sources around the 'net are suggesting its a physical hardware issue that cant be fixed with a firmware upgrade. I suspect now that this issue has been receiving so much international attention, Apple will release some info in the next week or so. I would suspect that their first response will be a firmware upgrade, and then they will wait it out a month or two to see what impact that has. Clearly, if that doesnt help we will see recalls (of the first generation 3G units) around the holiday season which wont be a good thing!

Serious Defect....

Almost certainly, customers will demand replacement phones (and want them free.) Apple/AT&T will probably try to make it conditional (new 2 year contract, for example.)

Either way, a serious screw-up.

No, the article says it likely isn't firmware fixable.

I would say it's likely that the author of this article has no idea about the gritty details of what can and can't be done in firmware. Because I just used the word "likely", my ass is covered if I'm wrong.

My Samsung ZX-20 has a Qualcomm (has qcomm sticker on it), and Motorola V3xx has a different 3G chip.
Motorola V3xx works well, Samsung ZX-20 drops calls (replaced phone 3x under warranty for the issue).

Re: Meat?

Yeah and you have to wonder whether this brokerage firm may have a financial interest in seeing Apple and/or Infineon take a hit. Oh wait, but that would be unethical ...

if you...

if you go into settings/network 3G and switch the 3G network to ON and there is no 3G service, you get 'NO SERVICE' until you power the phone off and on again.. Something is definitely wrong there..

That isn't universally correct.

I cross an EDGE / HSDPA boundary every day to and from work. I flip the 3G switch off most days when I get home because I'm on my WiFi, and turn it back before I leave. (Side note... wish that was automatic...)

I have never seen a NO SERVICE message when turning 3G on in an EDGE area.

With respect to the analyst, take anything they say with a grain of salt.

If he's an analyst at a brokerage firm covering AAPL, he could make a phone call or two and find out for sure what chip was actually in the phone. It's irresponsible for him to make any technical assumptions about solutions when he has no background in such matters.

I'll give Apple the time to see what they can do with this before passing judgment.

The article implies "According to Windsor, the problem likely isn't firmware upgradeable" (emphasis mine). I would like to know if there is any fact behind Windsor's speculation.

Same here, i have no problems going from HSDPA to EDGE as i do every day to and from work. The only problem i have is in downtown Kansas City, i can go from 3G to EDGE w/o warning standing in the same spot, then go right back to 3G.
