− | Although iPods have many other components, here we are only listing the components that might be relavent to cracking firmware encryption. If you have any suggestions for any other components to add, just post on the talk page or IRC. Links to datasheets are important if they can be found. For a visual hardware reference, visit the [[Hardware annotation]] page.
