    who said anything about a rev B?

    there were 3 versions of the 1st iPhone...4GB, 8GB, 16GB. All had the same hardware.

    We're in Rev. B. The 3G IS Rev. B. The first iPhone was Rev. A.

    I've read some articles that are suggesting that a firmware update may be released in September to improve the 3G reception.

    The article is stating there may be a hardware issue and should a firmware update not fix it entirely wouldn't the iPhone with the fixed chip be the 3G iPhone rev b?

    again, who said anything about a fixed chip??

    "Apple has not yet acknowledged the existence of 3G connection issues with the new iPhone and declined to comment for either article, leaving the details of the problem and Apple's plans for addressing it uncertain and subject to speculation for the time being."

    This explanation doesn't make sense. If I walk outside of my office right now, my bars would increase 3-fold. However, all my coworkers with their 3G phones are getting full bars inside the office.

    The chip is obviously too weak to receive adequate 3G signals inside any building...

    Actually, The first generation iPhone had many different models.

    Yes as already pointed out, a 4GB, 8GB and a 16GB.

    The signal bars are programmed by apple to correspond to signal strength that the chip is receiving. They could make the thing ALWAYS say 1 bar no matter what your "real" signal strength is if they wanted to, or they could program it to say 5 bars when, in fact, your chip is receiving such a low signal that it couldn't possibly function. So, the signal BARS really don't mean much if they aren't calibrated properly by apple to correspond to the actual signal strength that the chip is receiving versus what it needs in order to function properly. I think it's possible that Apple hasn't correlated the signal strength properly to the bars, and probably not just to the bars, but other parts of the firmware too (ie the part that decides if 3G is so weak that it should switch to edge) and that is part of the problem. Perhaps they didn't have a full understanding of the minimum signal requirements of the chip when they programmed it (or the information they had on the chip was inaccurate/conservative), or maybe the information was correct and they were just being extra conservative. Anyway, I think that is what the part of the quote in your post meant when it said "Apple programmed the Infineon chip to demand a more powerful 3G signal than the iPhone really requires." And this is probably what they will address with a firmware update. Whether or not it is true and/or will help everyone that is having problems remains to be seen.

    Right, because every single cell phone manufacturer uses the same method of calculating signal strength and converting it to the universally comparable and precise unit of "bars". :rolleyes:

    I understand that "bars" are essentially meaningless. However, it is true that I cannot receive or make calls inside the office/home, but walking outside would make the difference.

    Well that certainly is a problem then.

    I was having a problem with my first iPhone 3G...the battery life was extremely poor, and I got it swapped out for one with a very solid battery. It might just be a defective unit. Maybe try brining it into the store?

    rumor and speculation. That's all the article is stating.

    The truth is, we won't know until an update or a recall (or neither) actually occurs.

    That said, if this IS a handset hardware problem (and I still have my doubts on that), or even if it isn't and the network is to blame, the analyst who insisted a firmware update will do nothing to fix the problem is actually very wrong. Modern UMTS/3G radios are software driven, and can be tweaked quite a bit through the baseband firmware to change their performance characteristics. For the most part, the only thing that is fully hardware dictated are the frequencies at which the radio transmits. What and how that radio transmits on those hard-coded frequencies can be modified quite a bit. This is largely why CDMA carriers have an easy time upgrading their 3G equipment: a firmware update and ta-da! You've got EVDO revision A. the W-CDMA aspect of 3G on AT&T makes that part of the network very similar in its adaptability. 2 G GSM is less adaptable, but isn't totally stuck, either.

    But the analyst is just that, an analyst. Not an expert. If the analyst truly knew something about handset engineering, he'd be earning a lot more money by designing and making handsets, not by writing speculative investor's notes about them.

    Funny. I suggest you do some research first before making things up.

    You want to compare analyst's salaries vs. engineer salaries?

    You do know that analysts (especially analysts at investment banks who cover a particular sector) make salaries in the multi-millions right?

    The day I see an engineer make a salary of $10 million dollars.

    Ohh, looks like I hit a nerve with one of the newbies. :)

    We could, but at the end of the day, this thread has nothing to do with what analysts make, but rather what they know.

    I'll agree with you on this much: they make a LOT more than they know.

    The top 1%, yes. Quite a few of them end up also giving out wrong information, and then they get sued, investigated and fined. Then they end up with far less than millions.

    And you DO know that engineers - especially some of the top 1% at big companies - make multiple millions off patent royalties, and by later starting their own companies. Right?

    Anyway, don't hijack the thread. The fact remains: the analyst note doesn't cite anything authoritative. It's speculation. As is a lot of things that analysts guess about when it comes to Apple. False hopes (or despair) based on this is pointless.

    After all, isn't Apple supposed to be out of business by now? And where's our iPhone battery recall? And where are our tablet Macs?

    You know, I was wondering how much mileage, time wise, that Apple would be able to buy just by showing More Bars with a Software Update for the Same signal they now receive from the GPS chip. Would it be enough time for them to start producing iPhones with better chipsets?

    I know, I know, Apple would NEVER do that.

    I think it is reasonable to expect that the bars displayed should be a fairly accurate depcition of signal strength since ATT markets its service with the slogan "More bars, more places."

    On average analysts make far more money than engineers do. End of discussion. Is it justified? Probably not. Analysts can get sued, so can engineers. What's your point?

    Gasp! Analysts can start their own companies too. It's called hedge funds and private equity firms. This time, they won't be making millions. They'll be making billions.

    I'm not trying to derail a thread. Just picking apart your statements.

    Then attack the statements that have actual bearing on the thread. Or can you not? Probably the latter. So instead you go on a tirade, evidently over some personal agenda you may have about analysts. And that's called hijacking a thread.

    Now, contribute something useful or go don't contribute at all and go lick your personal wounds elsewhere, please.

    I just pointed something out in your statement. Nothing hostile. Just a simple statement.

    And then you went and had a hernia.

    Have a fantastic day.
