So I just aquired this GS3 after using a T-Mo LG G2. So my question is do I have the CDMA or GSM version? How do I tell? Can it be identified with the firmware or hsrdware version? The reason I ask is because Verizon is a CDMA network yet it has LTE sim cards in the phones. I just esnt to mske sure that I have thr correct vedsion before I stsrt flsshing my a$$ off. I already have root and working TWRP. Any help he here would be great.
