Just two days shy of the official launch of Apple's inaugural foldable smartphone, the iPhone Duo, lengthy lines have already started to snake around Apple retail outlets in numerous locations across the globe. Despite Apple's explicit warning that the initial offline store stock would be constrained, consumer excitement has not waned. Many have begun camping out days ahead of time, eager to be one of the privileged few to acquire the latest gadget. The iPhone Duo's pre-sale commenced at 8 PM on October 16, and within a mere minute of availability, all models were snapped up. In-store pickup options for launch day have also been depleted, while delivery times for some online purchases have been extended to as late as January next year. Priced starting at $1,999, the 256GB China variant of the device retails from 15,999 yuan, and the premium 2TB version commands a hefty 26,499 yuan, marking it as the most expensive iPhone ever released by Apple.
