|Samsung Gal S III|
In the past, Samsung has offered two handset designs based on whether they need 1X. Names are the same. Model numbers different.
I think a valid preview is in checking teardowns for the Galaxy S II models.
Sprint/VZ models use the QSC8085 baseband+PMIC+RF as the modem to their Exynos 4210 processor. But, if you check another teardown, the European version of the Galaxy S II uses the Infineon PMB5712 as part of the XMM6260 chipset from Infineon.
I don't think this author has it figured out yet. Especially since Verizon retailers around here expect their first handsets to arrive around July 1. unwiredview.com
ifixit.org << uses the Intel/Infineon PMB5712 RF transceiver and PMB9811X baseband. The Infineon version definitely uses Maxim power management chips. I've had Samsung and LG handsets meet the electronics recycling service due to flaky power or charging issues inside of 14months using Maxim.
Its interesting that Apple never combines power management chips (use Qualcomm PMICs) in mobile devices to save space. I'm not going to predict if the Vz/Sprint Galaxy S III will do the same.
