Scarcely had the first iPhone 4 CDMA sold by Verizon they were delivered to the first client repair specialists iPhone rushed over to the bone and see if it contained changes from iPhone to 4 GSM that is known since this summer.

After disassembly, it appears that iPhone 4 CDMA although very similar to 4 GSM iPhone has a number of differences that make Most parts are not interchangeable between the two models (Be careful if you order spare parts):

It is noted that the iPhone uses a four CDMA radio component of Qualcomm (MDM6600) which is actually able to communicate both on CDMA and GSM / 3G. As the only CDMA iPhone 4 has no slot for a SIM card needed for GSM, it is not question of use within this framework. By cons, this corroborates the rumors that the next iPhone, be it a iPhone 4S iPhone 5 or any other name could be compatible with CDMA and GSM parallel.

Other minor changes have been identified: the vibrator has changed location and model (according to iFixit nicer), the battery is similar in terms of capacity while losing 1.3 grams.
