Rare prototype iPhone, device lookup details state it's a PVTE stage prototype: "D33 PVTE KAROO NA CI SSV MAX A". D33 is the internal codename for this device, unclear what "KAROO" refers to. Sadly no external engravings on the phone, unclear if it was produced without it or if the shell was replaced at some point. Does show signs of use! Minor scratches on screen (see photos for full details), battery is reported as 86% health. Internal model number 993-32483, runs production iOS 16.0.2.
