Those eager Verizon subscribers that pre-ordered
the iPhone 4 are today starting to receive their smartphones. Not
surprisingly, the ever-resourceful folks over at iFixit
have already ripped open the iPhone 4 that they received today.
While there was some small changes visible from the outside
that we already knew about (repositioned antenna gaps and hold/volume buttons),
there's more going on underneath than just a switch from a GSM-based chipset to
a CDMA-compatible one.
IFixit reports that Verizon's version of the iPhone 4
features the Qualcomm MDM6600 chip [datasheet], which is the exact
same chip that is found in Motorola's
Droid Pro world phone. That means that the chip not only supports CDMA2000,
but it also supports HSPA+ which Apple conveniently disabled on this particular
The folks at iFixit reckon that it was probably easier for
Apple to simply go with a CDMA-only configuration now given the antenna
constraints in the current iPhone 4 design. But future generation of the iPhone
could very well support both CDMA and GSM which would simplify SKUs for Apple --
at least until LTE versions of the iPhone start rolling off the assembly line.
