We got our hands on the new iPhone 4 Verizon on the morning of February 7th, 2011. Compare this phone to our original GSM iPhone 4 teardown.

If you're happy with your current coverage, then by all means hang on to it! Keep it running if you drop it or your battery wears down using our iPhone 4 repair manual and parts.

Make sure to also check out the Verizon iPhone 4 Teardown video on YouTube!

This teardown is not a repair guide. To repair your iPhone 4 Verizon, use our service manual.

  1. The iPhone 4 is finally on Verizon!
    • The iPhone 4 is finally on Verizon!

    • We didn't try making a call, but we hear that this phone does make and maintain "complete calls."

    • On the back, Apple's removed the visual warning to not throw your iPhone 4 in the trash.

      • These logos tend to relate to non US countries. The "recycling bin" logo, for example, is for the European WEEE Directive. Since the CDMA model is not sold in countries which require these symbols, they don't appear.

    • Apple's updated the model number (from A1322 to A1349), but there's not much externally to let us know we're dealing with a Verizon iPhone. Is this the first Verizon phone without "Verizon" emblazoned on it?

  2. There are a few external differences, reflecting the different antenna design of the new CDMA iPhone.
    • There are a few external differences, reflecting the different antenna design of the new CDMA iPhone.

    • CDMA, or Code-Division Multiple Access, is actually just a channel access method standard. When most people (including us) say CDMA, they usually mean CDMA2000, which is a family of 3G communication standards that run on top of the CDMA mechanism of utilizing airwaves. Confused? Unless you're an RF engineer, the distinction probably doesn't matter to you.

    • In the US, Sprint and Verizon use CDMA. T-Mobile and AT&T use GSM.

    • Worldwide, GSM (which stands for Global System for Mobile Communication) is far more popular. But CDMA is still used in 40 countries, primarily in Asia. China Telecom is the next largest CDMA carrier, with over 90 million subscribers.

    • The SIM slot is gone. According to Apple, the SIM card and SIM tray were the only user-serviceable parts in the AT&T iPhone 4. Apple now says "iPhone does not contain any user-serviceable parts." We believe you have the right to repair your own hardware, and we'll have a repair guide available right away.

    • We believe the additional break in the antenna enclosure on the right side of the phone is a result of the switch from GSM to CDMA. An antenna's operating frequency is directly dependent on its size and geometry, so the change-up required an antenna overhaul.

      • The AT&T GSM iPhone has three differently shaped antennas, which enable the phone to communicate on UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz) and GSM/EDGE (850, 900, 1800, 1900 MHz).

      • The CDMA iPhone, which has four antenna segments (two "U" shaped pieces at the top and bottom, and two straight bars along the edge) only needs to operate on 800 and 1900 MHz for CDMA EV-DO Rev. A.

      • Both phones use 2400 MHz frequencies for Bluetooth and 2.4 GHz for WiFi and the 1.575 GHz frequency for A-GPS.

    • Only time will tell if this new antenna design helps combat the reception problems reportedly plaguing AT&T's GSM iPhone 4. However, there is no reason to expect that it would as the problem reportedly does not occur with the GSM iPhone on other GSM networks around the world.

    AFAIK the 802.11n radio on the iPhone 4 doesn't supports the 5Ghz frequency band

    So how can one find the SIM card # on the A1349 model?

    • After the screws are out, the back cover slides off easily.

    • Unfortunately, no surprises be honest, we were kinda expecting some magical cloud of pixie dust...

    • At a quick glance, things don't look too different in here. But the fact remains, they are not identical. If you can't tell, the Verizon iPhone is on the left.

    • Apple has removed the counterweighted vibrator motor in the corner of the phone and switched to a different vibrator design that's now placed near the battery connector.

    • You can also see the re-located antenna notch in the second picture.

    • The back covers are very similar, but not interchangeable.

    • Curious which phone you should take with you on your epic around the world journey?

    • Wikipedia lists just 58 CDMA carriers in about 40 countries, and almost 300 GSM/UTMS carriers.

    • If you only have room for one phone, stick with the GSM version. But, if you are desperate for more reliable coverage in the US, Verizon will provide you with a free loaner 'country compatible' phone for up to three weeks.

    "Wikipedia lists just 58 CDMA carriers in about 40 countries, and almost 300 GSM/UTMS carriers.”

    If you want to use ‘3G’ or data CDMA as an option drops considerably. Many countries and carriers went from CDMA to UMTS/HS*PA, not EV-DO.

    • Once you're inside, the battery is very easy to replace. The battery is listed as the same 5.25 Watt-hour capacity, but does have a new model number (616-0520).

    • The new battery also weighs less; it shrunk from 26.9 grams to 25.6 grams.

    • Disconnecting the Wi-Fi antenna.

    • For enough room to disconnect the Wi-Fi antenna on this phone, the ground finger must first be removed. Apple moved this finger out from beneath the battery connector, making battery replacement that much easier.

    • The Wi-Fi antenna and chip are perhaps the only RF components of the phone that did not receive a revamp. The board utilizes a Broadcom BCM4329 - the same chip found on the GSM iPhone 4. This antenna is nearly identical to the unit found in the GSM iPhone 4.

    • The speaker chamber and cellular antenna assembly come out easily enough.

    • After removing a metal shield, a sea of connectors becomes visible.

    • Thankfully none of them are tricky to disconnect, so disassembly is not especially challenging. With the help of a repair guide to keep screws and pieces straight, repairing this phone shouldn't be too difficult.

    • The logic board can finally be lifted out of the iPhone.

    • Verizon iPhone 4 logic board on top.

    • Although it's the same form factor, this is definitely not the same board. Conspicuously absent is the SIM slot. That's freed up a lot of space for something.

    • We'll get the EMI shields off soon enough...

    • Apple used custom molded rubber bumpers between the chips and the EMI shields presumably to quell any interference between analog and digital circuitry.

    • Thanks to our friends at UBM Techinsights for providing us with some chip identifications.

    • The front side of the Verizon logic board (on top) contains:

      • Apple A4 Processor

      • Qualcomm PM8028 Power Management

      • Dialog D1815A Power Management IC (Apple branded 338S087)

      • 343S0499 - Texas Instruments Touchscreen controller - Apple/TI, part is #343S0499/#F761586G (an up-rev from earlier # F761586C of the iPhone 3GS)

      • SKY77711-4 - Skyworks poweramplifier module for CDMA/PCS

      • SKY77710-4 - Skyworks power amplifier module for dual-mode CDMA/AMPS

    • The back side of the Verizon logic board (on top) contains:

      • Qualcomm MDM6600

      • Toshiba TH58NVG7D2FLA89 16 GB NAND Flash

      • Toshiba Y890A111222KA

      • RS KMOD16104 - The logo on this package appears to be that of Murata's. We suspect that this contains the Broadcom BCM4329 that reportedly provides Wi-Fi/Bluetooth connectivity.

        • Adding credibility to this statement is the fact that we found this chip last June in the GSM iPhone 4 and that Murata and Broadcom have had RF partnerships in the past.

    • Here are the brains of the iPhone.

    • The A4 markings read N31BNPZ5 APL0398 339S0123, front and center.

    • ST Micro's 2052 33DH 0BGDL (three-axis accelerometer)

    • ST Micro's AGD8 (L3G4200D 3D gyroscope)

    • 10C0 047A 0315

    • Cirrus Logic 338S0589 CLI1495B0 Audio Codec (Apple branded)

    Clearly a new A4 version from Apple:

    - different Apple PoP part number 339S0123 (original iPhone 4: 339S0108)

    - different Samsung DRAM incorporated K4265J1PB-50-F (original iPhone 4: K4X4G643GB)

    - same processor SoC die marked as APL0398

    Guys...I think you miss the BCM4329 on one of the module as the WIFI chip bigtime...... the readers are not well inform.

    I have solder an A4 CPU from iPhone 4 CDMA to iPhone 4 GSM after restore it works as it should.

    • Like the Apple TV, there is an interesting set of unused solder pads near the edge of the logic board. These are likely used for testing during development.

    • The Qualcomm PM8028 chip works in conjunction with the Qualcomm MDM6600 to provide wireless data connection to the phone.

    • Dialog D1815A power management IC is in the Apple branded package labeled 338S0876.

    • Avago A2FIO46

    • Skyworks SKY77711 and SKY77710 power amplifiers

    • These photos belie how small all these chips are. We'd be lost without the help of a good camera lens and a magnifying loupe.

    • The Qualcomm MDM6600 chip supports HSPA+ data rates of up to 14.4 Mbps and CDMA2000® 1xEV-DO Rev. A/Rev. B

    • This is the same chipset as the Droid Pro world phone. It supports both GSM and CDMA—which means that Apple could have supported GSM!

    • Why didn't they? It may be that it was easier to design antennas for a CDMA-only phone -- this phone supports two cellular frequency bands, while Apple supports five bands in the GSM version.

    • Of course, there's no way it could be a real "world phone" without a SIM card slot.

    I'll be very interested to see what modders can do. Maybe with asimple hack or accessory it'll be a world phone

    • Holy haberdashery, Batman! The iPhone 4's vibrator received a complete makeover.

      • Rather than using a rotational electric motor with a counterweight, the Verizon iPhone appears to utilize a linear oscillating vibrator for call/message alerts. Based on the patent information around this technology, we think this may be a Samsung part.

    • Our tests show that the new vibrator has quieter, softer feel, and makes a better sound when on a table.

    • The display assembly appears to be identical to that of the GSM iPhone 4 at first glance.

      • UPDATE: Upon further investigation, the mounting tabs are in drastically different locations for the two display assemblies. This means the two assemblies are definitely not interchangeable. The Verizon display is on the left in the second photo.

    • We'll have replacement parts and a detailed repair guide posted very soon.

    This right here is the $100,000 question. Stick one of your existing AT&T iPhone 4 front assemblies on this bad boy and see if it fires up!

    You guys (rab777hp and jonathan) are joking, right? There is no way that can be done in the current config. h/w and s/w wise. The VZW iPhone doesn't have the front end parts for UMTS at all and you can't just connect some ATT iPhone front end to it cuz the interfaces and architecture used by the 2 phones aren't compatible. Besides, the s/w (protocol stack & firmware) for UMTS are not resident in the VZW iPhone version. Once again, you can't just borrow firmware from the ATT iPhone and try to shove it into the VZW version. They are simply not compatible between the 2 phones. The most one can say from the choice of this chip is that Apple is positioning itself to use this chip as a reconfigurable modem (at the time of manuf.) to support CDMA and UMTS when the iPhone5 comes out.

    My names Kyle, I have managed to remove the vibrator from the bottom and cut out the mounting tabs for the logic board that kept it from seating. Once I set the board in I did a little bit of ribbon folding to put them on the gsm board attached the wifi antenna from the gsm and put the battery in it and it fired right up. Now the only downside at all is that you have to put the SIM card in when you're putting the board in unless you want to cut a slot in the side and due to water and everything I decided against it. Just modify the tray and slide the sun card in the slot and put the phone together and you're good. Oh yeah, and you have to cut a tab off of the back glass if you want to use your att one.

    • Verizon iPhone 4 Repairability Score: 6 out of 10 (10 is easiest to repair)

      • The iPhone 4 is held together primarily with [lots of] screws, sans tabs, and limited adhesive.

      • The rear panel and battery are both easy to remove and replace (provided you have the right screwdriver).

      • Apple is using Pentalobe screws to secure the rear panel and keep people out.

      • The LCD and glass are fused together, making repairing a cracked front panel more costly.

      • During disassembly, your finger oils interfere with the iPhone 4's RF grounding contact points, so we recommend you wear gloves while performing any repairs.

"On the back, Apple's removed the visual warning to not throw your iPhone 4 in the trash."

This is the <a href=">WEEE</a> directive logo which applies to electronics sold in (most) of the EU. The Verizon iPhone is only sold in the USA at present so the directive doesn't/can't apply.

Hey guys this is a question! I need help! I have (two) IPhones. I need to swap the logic boards. Will it still work without a SIM card since the model:A1332 has one and the logic board I'm installing has no SIM card?
