Slideshow: LIVE: VERIZON IPHONE 4 TEARDOWN
BYTE's colleagues at UBM TechInsights are tearing down the Verizon iPhone 4, the CDMA version of the iPhone that Verizon began shipping to its own customers late last week. Beginning from the out of the box experience, the following photos show the process of taking this baby apart, step by step. This is a full tear down, so you can get a real look at the ICs and the design decisions engineers made. In this case, we were particularly interested in the CDMA aspect of the phone, comparing the desi

What you see when you open the box.
A look at the packaging.
The back of the Verizon iPhone 4.
Comparing the Verizon edition of the iPhone 4 (top) with the AT&T GSM version (bottom) -- notice the change to the antennae design. Notice also the additional breaks to the phone enclosure. This indicates a change in the antennae methodology.
The bottom of the Verizon iPhone 4 is the same as the AT&T version.
Removing the touchscreen overlay reveals the inside of the iPhone. As you can see, the device still uses the Lithium Ion battery, which takes up more than 50 percent of the space inside.
Here we can see one of the image sensors at the top of the board -- as well as the microphone at the bottom.

The main board of the iPhone 4 CDMA version reveals a major design win for Qualcomm. The Qualcomm MDM6600 can go full out multi-mode supporting GSM/GPRS/EDGE, CDMA, HSDPA and HSPA+, as well as EV-DO.
Here we see the brain of the iPhone 4 has remained unchanged -- the A4 processor (developed by Apple and Samsung) remains unchanged in this model of the iPhone. We also see more technology from Qualcomm with its power management IC on the system -- PM8028. So the Verizon iPhone is a double design win for Qualcomm -- both Qualcomm's power IC and data chipset are featured in the Verizon iPhone 4.
