The back side of the Verizon logic board (on top) contains:

Qualcomm MDM6600

Toshiba TH58NVG7D2FLA89 16 GB NAND Flash

Toshiba Y890A111222KA

RS KMOD16104 - The logo on this package appears to be that of Murata's. We suspect that this contains the Broadcom BCM4329 that reportedly provides Wi-Fi/Bluetooth connectivity.

Adding credibility to this statement is the fact that we found this chip last June in the GSM iPhone 4 and that Murata and Broadcom have had RF partnerships in the past.
