Icon rewind is an online service that can help you retrieve the icons of the classic iPhone apps. Yes, there are several shortcuts.
Icon rewind doesn't have a lot of icons. It's probably just the head app. But with early wallpaper, it's very nostalgic.
It's also easy to use. Open the icon rewind website, click the desired icon, and a new page will be opened. Choose to open it with Safari, then click the share button, and select Add to the main screen.
