On May 17, 2011, in iPhone, by admin

Because of slight differences between the CDMA and GSM-based iPhone 4, not every case that fits the AT&T version of the phone will work with a Verizon model. But don’t worry, Verizon iPhone 4 users — we’ve begun testing and rating cases designed to fit your phone.

An event that has become as much a staple of summer as ice cream, lawn sprinklers, and the last day of school appears likely to be put off this June, reports say. Apple’s regular schedule of iPhone refreshes since 2007 may have been upset by the February release of the CDMA version for Verizon Wireless.

Apple Releases iOS 4.3.2 (iOS 4.2.7 for Verizon iPhone)

Written by Eric Slivka


Apple today released iOS 4.3.2, bringing several minor fixes and improvements to Apple’s operating system for mobile devices. The build number is 8H7 for the majority of devices, with the CDMA iPad 2 receiving Build 8H8. A separate iOS 4.2.7 build 8E303 is also available for the CDMA iPhone 4.

This update contains improvements and other bug fixes including:

- Fixes an issue that occasionally caused blank or frozen video during a FaceTime call
- Fixes an issue that prevented some international users from connecting to 3G networks on iPad Wi-Fi + 3G
- Contains the latest security updates

BGR noted one week ago that iOS 4.3.2 was expected to debut within two weeks and reported earlier this week that the update would fix the issue with CDMA iPad 2 connectivity and FaceTime glitches.

The Verizon iPhone was likely just the first step in Apple’s broader push into the CDMA handset market. And while the company stands to reap the most benefit from that first partnership, there are plenty of other opportunities abroad for CDMA market success. J.P.

Teardowns Detail Minor Differences Among Wi-Fi, GSM, and CDMA iPad 2 Models

Wednesday March 30, 2011 10:02 AM EST
Written by Eric Slivka

iFixit yesterday announced that it has completed teardowns of the GSM and CDMA versions of the iPad 2, joining the teardown of the Wi-Fi version performed on launch day earlier this month. Rather than posting an extensive walkthrough of each model, iFixit focused on the few areas in which the various models differ from one another, related of course to the cellular connectivity needs or lack thereof.

The most obvious physical difference between the 3G models is the micro-SIM card slot along the upper left edge of the GSM model, required for providing the device with subscriber information. The micro-SIM card slot itself is actually attached to the headphone jack cable on the GSM model, while the CDMA model lacks the slot entirely as subscriber information is instead hosted directly on the WWAN board inside the device.


iPad 2 antenna configurations: GSM (top), CDMA (middle), and Wi-Fi (bottom)

Given the differences in frequencies used for the GSM and CDMA network standards, it is also unsurprising that the two 3G iPads offer slightly different antenna configurations, with the CDMA version offering one more antenna than the GSM version, similar to the iPhone 4.


iPad 2 logic boards: Wi-Fi (top), GSM (middle), and CDMA (bottom)

And finally, the three iPad 2 variations also exhibit differences in their logic boards, with the 3G models containing WWAN board extensions housing the hardware supporting cellular connectivity. Unsurprisingly, the CDMA model contains essentially the exact same chips, including the Qualcomm MDM6600 baseband chip, as the CDMA iPhone 4. The GSM model, on the other hand, primarily relies on Infineon chips for its connectivity.
