"Apple should be able to retain about 95% of the design of the CDMA iPhone," said Wayne Lam, a senior analyst with IHS iSuppli, talking about the next version of the iPhone, which experts believe Apple will introduce June 6.

The big news from iSuppli's teardown -- the practice of taking apart consumer electronics to see which components were used, how they were constructed and how much those parts cost -- is the move to a Qualcomm baseband processor, the silicon that allows the smartphone to make and take calls.

Until Apple debuted the Verizon iPhone, which operates on a CDMA-based cellular network, the company had relied on Infineon for the phone's baseband processor.

Lam said that it's likely Apple's next iPhone will work on both CDMA and GSM technologies, with only minor modifications to each networks' model. AT&T, and most of the world's cellular networks, use GSM.

His take: Because the Qualcomm processor supports both CDMA and GSM, Apple can slap the same processor in both CDMA and GSM iPhones.
