Teardown of iPhone 4: 512MB RAM Confirmed and Other Notes

[ElBerserko]

Wrong part number listed

Look at the picture closely on the left side (http://s1.guide-images.ifixit.net/igi/SycKSNmuDADWD2DR.huge). There is a TriQuint chip, but the part number is TQM676091.

I cannot find any reference to this part number, but keep in mind TriQuint does make GSM modules. I see nothing here that indicates there is a CDMA module here. It's a typo.

I wonder why the storage capacity is no longer on the back?

 

[severe]

the question is will it be jail broken quickly

Check yesterday's news.

It's probably cheaper for Apple to make one iPhone back that can go on either phone than two the have to be specially marked.

Dude, the screen's Transparent Aluminum !!!

"Is that worth something to ya laddie? Or should I just punch up clear?"

 

[andyblila]

the A4 is clocked at 1ghz?
Are you sure?
I seriously doubt it.

iFixit says 1 Ghz.

The Plot Thickens...

So perhaps the phone supports CDMA and GSM which is probably why Apple don't want the FCC to release the approval specifications for 28 days...

 

[Thex1138]

The metal frame looks beautifully engineered...

So precise.

Apple engineers and fabricators really know their stuff.

Yea that's odd. The only way to find out how much memory is in an iPhone 4 now is to go ALL THE WAY into "About" in settings!

I still was a little surprised to see that though.

32GBytes is really 29.80GB in binary

The teardown notes that the capacity is 29.06GB.

If you take 32,000,000,000 bytes (32GB) and divide it by 1024 three times (1024MB, 1024KB, 1024B), you'll get 29.80GB... iFixit mentions that they saw 29.06GB of space left. Does that mean iOS4 is 0.72GB? That's a large OS!!!

I can't wait to get mine.. i am also interested to see them blend this sucker. blend that iphone 4!! wohoo. I really hate they do it to apple's products but i wonder how this one will stand up the it..

dang rcandre2 you beat me too it!!

 

[irwinm]

the list has now been removed from both iFixit and the catalogue at chipworks - definitely feels like a false alarm (but exciting for half an hour )

 

[CalebF]

Didn't Gizmodo already do this a couple months ago?

Step 17 at iFixIt.com says the following...

Step 17
Triquint TQM613029 CDMA PA-Duplexer Module.
Avago FEM7758 Front End Module
Triquint TQM13029 CDMA PA
Atmel M88PA MCU with eFlash
Silicon Image P1U0941 HDMI Processor
Samsung KBY00U00VM NAND Flash

Um, why does it say CDMA? Shouldn't it say GSM? Is this CDMA capable? AT&T is GSM. Or is this some weird other CDMA part?

Just curious as to what I am missing. Or are they wrong? Or what?

Don't get your nuts in a bunch:

They just truncated the name, WCDMA is the tech paired with GSM to provide high speed download and upload packet access (HSDPA/HSUPA), the so-called 3G network for ATT and T-Mobile.

If you take 32,000,000,000 bytes (32GB) and divide it by 1024 three times (1024MB, 1024KB, 1024B), you'll get 29.80GB... !

A note: it's not a physical hard drive with bogus market decimal powers. So it's not 32,000,000,000.

Flash memory chips come the same as all memory chips... in powers of two: 32GB = 2^35 = 34,359,738,368 bytes

Apple seems to deliberately ignore some of that space, however. My guess is that it's partly because something like 10% of each Flash device's memory can be missing from the factory and still pass quality control. (It's the only way to get less expensive memory yield.) Can you imagine the marketing backlash if your friend had the full 32GB but your unit only showed 30GB?

 

[jtp098]

Silicon Image P1U0941 HDMI Processor??? huh

 

[EViL LeViaTHaN]

I really want to know if this has dual GSM and CDMA? That would be the biggest news ever. I have to believe it's a mistake or it doesn't really mean CDMA, LOL.

I do not think that word means what you think it means.

division multiple access (CDMA) is a channel access method utilized by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply CDMA), which use CDMA as an underlying channel access method.

Thhis thread goes into more detail than my short explanation above, everyone freaking out should definitely read.

iFixIt also pointed out the magnetometer in the iPhone 4 is supposed to be a newer, more accurate one than in the 3GS. Might want to add that to the front page.

It's probably cheaper for Apple to make one iPhone back that can go on either phone than two the have to be specially marked.

Yeah, I posted about that awhile ago. Still, it's been on every iProduct since the original iPod, so it's sad to see it go.

Ok I was wrong, it was a CDMA chip incorrectly posted, not WCDMA. This from the author "That CDMA information was incorrectly copied from a different report. My apologies; it has been removed.

and ifixit changed it oh well no cdma

512MB RAM is very impressive considering that's what high-end laptops were stocked with several years ago.

512MB RAM is very impressive considering that's what high-end laptops were stocked with several years ago.

My very old PC had 64 MB of RAM and i was running Windows 98 and Office on it.

This A4 chip should be capable of running a more complex desktop OS.
