This cloth was included as an accessory with brand-new iPhones at the time, hidden alongside the user guide paperwork. Unlike the Apple Polishing Cloth, this wasn’t $19 and was included for free with every iPhone purchase.
This one has seen it all. No internals unfortunately, just a battered shell.
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!
