iPhone 4 already has CDMA chip?

Something is up, no reference at all online.

and read this along with it ->

Apple Tells FCC: There's more to the iPhone than the Public Knows

Forgot about this....does this apply to iFixit also?

Not quite..


The TriQuint chip is for WCDMA/HSUPA...same as the 3G/3GS

how do u know that?

 

[PureRED]

how do u know that?

Because it's available on the internet. Le sigh.

lol i understand that OTHER triquint chips do that... how do we know THIS triquint chip does...

something is still mysterious here about the FCC. 45 days. cant return in 30.

somethings gotta be up. maybe some....deception.

OMFG

THE DESCRIPTIONS SAY CDMA

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

Good night

iPhone 3G

im sure im going to get a reply about how its "more complicated than that" but

the end numbers of "...029" dont match with any in that diagram.

I love you.

HSUPA Support

Meanwhile, iLounge has noted that the iPhone 4 supports 3G HSUPA (High-Speed Uplink Packet Access) for its uplink. iLounge cites a theoretical maximum of 5.76 Mbits/second. Meanwhile, the iPhone 3GS is limited to only 384kbps. Any faster uplink speeds will obviously help out in emailing high definition video clips over 3G networks.

If you would compare the architecture of both, while slightly different and with slightly different numbers, I think you can reasonably ASSUME that the HSUPA chipset in the 3G/3GS is similar to what we're seeing here. A CDMA set would require something additional and is not shown, just the Skyworks GSM chipset.

 

[lord patton]

now at&ts early upgrade eligibility/ early termination fee increase is making sense...

exactly!

I'm as much of a free marketer as you'll find, but even I would never trust a company to be "generous".

well what do you suppose the whole "keeping the FCC records on lock" thing is about?

But what the heck is the mysterious Triquint TQM676091 chip for? A custom chip made for Apple? And, if so, what's so secretive about it (or other chips) that caused Apple to ask the FCC to withhold disclosure for 45 days?

this is what I'm saying the evidence indicates more than one carrier in the US

 

[Lastof]

Oooo. They have changed the listing. Now just reads

Skyworks SKY77541 GSM/GRPS Front End Module

Clearly they finally spotted their error (or just got around to replacing a misleading placeholder).

 

[iTouch]

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.

I jumped on the conspiracy theory bandwagon too --

... but, I'm just not seeing CDMA architecture here... just GSM and HSUPA.

how in the hell do they go from like 8 to 2?

*edited* added 1.

 

[angrytoothbrush]

they arent even listing the chips that are there now

EDIT: ok nvm they are adding more

again att did the same last year. i dont see Verizon do i?

 

[41qser]

lol they're updating it as we speak...



it will happen, people. just not tomorrow.

WTF are these people doing!
