I've been wanting to start a repair business for a long time. An opportunity came my way and I started up. I've been focusing on refurbing damaged iDevices and repairing customer units.
The guides on iFixit.com are awesome! It seems that anything that is missing in the guide is in the comments. This makes repairs go really smooth!
