You may remember Scotty Allen and his excellent YouTube channel Strange Parts (one of the best recent additions to my subscription list) for a video he shared in September about adding a headphone jack to the iPhone 7. After modding his iPhone with a custom case and backlit logo, Allen is back with the “ultimate” upgrade: after many failed attempts, he was able to replace his iPhone’s built-in storage, expanding it to 128 GB (up from 16 GB).

As with his headphone jack video, this is not a process that most people can try: it involves soldering, obtaining a compatible iPhone flash storage unit, and a device to manipulate data directly on the chip. However, this is a fascinating look into the world of spare iPhone parts available in Shenzhen, and I highly recommend watching the video below.
