This iPhone runs CarrierOS and has DEBUG modem firmware. It has antenna testing holes and was manufactured 2 weeks before the official release date of the iPhone 7.

Originally, this iPhone was completely trashed. It had a badly swollen battery, which ended up ripping all of the screen cables, and it was literally thrown into a bulk lot of iPhones as a “free gift”. I replaced the battery and screen with genuine replacements and now it works great!

This iPod was manufactured in 2004, whereas production iPod shuffles were made in 2005. It’s in an unreleased storage configuration (256MB), missing regulatory markings, and has the text “DVT2C” engraved.

Sometimes a specific lot of prototypes will appear, and for weeks or even month long periods of time they're readily obtainable if you know where to look. But then once the stock dried up, they basically disappear. Years later, even seeing a single prototype unit from one of these lots can become extremely rare.
