iPhone 4 already has CDMA chip?

Guys... I got it.... The perfect conspiracy theory...

Apple release an iPhone compatible with Verizon, keeps it secret. The on June 24th, when they KNOW everyone is going to tear it to bits announces that Pegatron will manufacture partner to keep up with the demand expected from Apple going with Verizon, the same day Pegatron goes public....

I agree, I don't trust any of the Pegatron rumors, as they are probably floated by Pegatron themselves to boost the IPO. The timing is just too convenient for Pegatron. Verizon iPhone rumors come up basically weekly and have for 3 years, and yet nothing has ever been announced.

If there is a Verizon phone it won't be out for at least 6 to 9 months. A lot of these PAs are "custom made" for their customers. They could very well be a current PA just rebadged. But a customer like Apple takes bid from multiple semiconductor companies. Whoever can design the specs that Apple wants at the lowest price could very well get the bid. If you notice that the PAs are from multiple companies. Nokia likes to do this. And even if it's based off a current PA, Apple could want different material(s), additional switch, coupler etc. On paper it seems like a simple additional/change but you can run into multiple problems, high failure rates etc that could extend the product cycle. I think 9 months is safe to say a Verizon phone could go into full production. It could be sooner but I don't know how the AT&T exclusivity kicks in. Also PAs that are relatively problem free can have significant failures when it does go into production.

Lol, yeah, but at 2:15am and having no job for the summer while home from school, I have nothing else better to do :p

No... The white iPhone is Verizon only! .....

Think about it, has anyone seen apple demonstrate a white iPhone?

Walt Mossberg has a white 4, you can see it in his video review he just posted today. It's definitely an ATT phone as Unkie Walt spends the better part of the article talking about how the weak point of the iPhone is the ATT network.

Hey folks,

My apologies on the incorrect information that was on the teardown for a little while. We're in a rush to ID a lot of components, and one of our engineers accidentally added some EVO part numbers to an internal document we were referencing. Then another engineer, not realizing it was incorrect data, posted them to step 16 of the teardown without double-checking it. The information has been corrected.

I know you guys put a lot of trust in us on these things, and we do our best. Thank you for your understanding. This is a collaborative, in-the-moment effort. Your comments are extremely useful, and we incorporate error checking from all of you as we do our analysis. Please don't leave comments on the teardown or ping us on twitter if you see any more errors.

unacceptable. error caused me to loose 30 minutes of studying about the diencephalon and the brain stem. THANKS ALOT.
 
just because kweins says it was a mistake about the evo thingy doesnt mean the triquint chip is no longer in the phone it is. Sounds like to me hes covering his ass.
 
I am switching to AT&T, hopefully if a verizon phone is announced I will have some thinking since I won't be sure to go back or no. I hope something is announced soon.

WCDMA is also CDMA. Why would a GSM phone have a regular CDMA2000 chip in it?

NO W-CDMA ≠ CDMA

A better question would be.... Where is the GSM chip? This is a mistake from ifixit.

W-CDMA = GSM

JoshHawn said:
OMFG :eek:

THE DESCRIPTIONS SAY CDMA :confused:

okay then... I officially declare this topic not interesting to me anymore.

Good night :D

No, the descriptions say WCDMA....not the same.

I mentioned Skyworks before about the GSM and WCDMA and it wasn't a big deal before. But now it is?! Triquint is really small compared to Skyworks or Qualcomm or RFMD. It's not surprising there are multiple WCDMA aka 3G chips since it has to cover multiple bands. Skyworks was responsible for the previous iPhones and the iPad I believe. As far as making a CDMA phone there has to be a redesign. But there are hybrids being made that are GSM/WCDMA in one solution being designed.

ALL W-CDMA phones are GSM/W-CDMA because W-CDMA is a GSMA standard!

Wow...really? Are those black helicoptors I see out your window? Take the tin-foil hat off dude.

You guy are so freaking confused. Go read up on W-CDMA a bit. It is the new air interface that the GSMA adopted to replace TDMA. AT&T has been switching over to it for several years now. (This is why voice quality improved.) While based on the same technology (Code Division Multiple Access), it is NOT the same as CDMA.

It's more about HSUPA...

If this were going to be a nextgen Verizon phone, we'd see evidence of LTE. CDMA is on its way out...

What's more about HSUPA?

The point I'm trying to make is that some of the people in this thread are confusing W-CDMA and CDMA thinking the presence of W-CDMA chips means that somehow this phone could work on a Verizon network when it absolutely could not.

Why do people keep saying that? It's no more on its way out than the current GSM standards (the difference is that the existence of the GSMA means they continue using the same "GSM" name despite the fact that the base GSM technologies were abandoned a while back). All technology gets retired over time. Both the current GSM and CDMA standards will eventually be replaced by LTE. In the meantime, the legacy systems will need to be supported so we will see phones that support LTE as well as W-CDMA or LTE and CDMA.

Thanks for telling me something I already said and know. I know the iPhone uses GSM/EDGE or 2.5G Quad Band GSM along with a couple of WCDMA aka 3G. Don't be surprised that the WCDMAs are used in other phones including CDMA. A lot of parts are just rebadged. They could be the same part with an additional switch, coupler, better material. It could the same part but used in low end phones or high end phone depending on the spec the customer wants and is willing to pay.

That particular statement was not directed at your quote. (go back and look at the quote it was beneath)

However, I'd like to address this statment:

That's like saying a hybrid Fuji/Apple fruit is being developed. The Fuji Apple is already an Apple. W-CDMA is already GSM.

Perhaps it would be clearer if we stopped using the generic term "GSM" as it really is vague given that it's really no longer a technology but more the name of the governing association.
 
Some dude at iFixIt was just sitting there LAUGHING his butt off at all the verizon iphone fans :) That's just cruel!! :p

My friend works at a semiconductor company and he calls it GSM, which is by default GSM/EDGE. WCDMA is a separate PA. IF it were an all in one solution then I would agree. They are 2 separate components for now and he works at one of the largest semiconductor companies. A good portion of their business are cell phones.

Hmmmm....so your original statement was just to point out that there are chips being designed that combine the 2G and 3G PAs into one chip? That was unclear to me. Sorry for rolling you up into my list of corrections.
 
Why not just change the thread title to:

iPhone 3G, 3GS, and iPhone 4 all have WCDMA

or

This just in, iPhone 4 supports 3G standards

whats really the pro's of going to verizon anyways?
Click to expand...

Apple:

1. Chance to multiply iPhone user base ($$$)
2. Multi-carrier term negotiation leverage

Me:

1. No epic cancellation fees
2. Not having to "settle" with an Android phone
3. Use of working network for first year until it is similarly bogged-down
4. Verizon capable iPhone means more carrier competition, both economically and in terms of network upgrades/performance

AT&T

1. Slightly smaller user base because of crossover, but less strain on network


*EDIT*

The rollout of LTE is being planned by Verizon, not being implemented as of yet. Apple would not utilize precious logic board space for the necessary chips this early in the game.
 
Yeah, well that's the thing. I think if CDMA were to happen, it would've been in 2007. For an almost obsolete technology, it wouldn't make sense to make iPhone 4 or 5 CDMA. iPhone 5 as LTE (3.9G) might make sense though, if there's enough network coverage + backwards compatibility.
