The new iPad 4G contains Qualcomm's MDM9x00 Basebandby Brian Klug on March 8, 2012 1:08 AM EST
A while back we speculated that Apple would use Qualcomm's 28nm MDM9615 basband for future iDevices with 4G LTE. The part made logical sense at the time, in part because of its 28nm process and compatibility with all the relevant air interfaces. Now that the restore .ipsw images have been posted and are available for download, I took a peek inside and did a little bit of forensics. It turns out that Apple has gone with Qualcomm's MDM9600, and has given the device codename Maverick (as opposed to Trek for MDM6610). This part still contains UE Category 3 LTE, CDMA2000 1x/EVDO Rev.A (and B), GSM/EDGE, and WCDMA/HSPA+ all the way through DC-HSPA+ 42 Mbps. It's a 45nm 13x13mm part we've seen in numerous other 4G LTE devices thus far.
You can see in the gallery above (or examine yourself by extracting and using your favorite hex editor) that there are numerous 9x00 and 9600 references in the build path throughout all the relevant .mbn files. As a reminder, AMSS.mbn corresponds to Qualcomm's Advanced Mobile Subscriber Software, which is exactly where you'd expect to see such references. The baseband given is MDM9x00 to be specific, though again MDM9200 and MDM9600 differ only in whether CDMA2000 1x/EVDO is enabled. I wager we'll see the AT&T, Verizon Wireless, and the international model using the same baseband but ship with different modules with different sets of power amplifiers.
