MDM6600 in an iPhone 4

This is the Qualcomm MDM6600 baseband chip used in CDMA devices.

Known Firmware Versions

iPad 2 (CDMA) and iPhone 4 (CDMA)

NOTE: The iPhone 4 (CDMA Model) supports all versions (except 4.3 and 4.3.*), while the iPad 2 (CDMA Model) exists since iOS version 4.3. Nobody tested if 4.2.x would run on an iPad 2 (CDMA), since you cannot downgrade without SHSH blobs and Apple has never signed them for it.
