The retro iOS ’86 concept created by Russian designer Anton Repponen that was shown last week, it is now available thanks to iTheme who replicated the concept and made it possible to download. In order to have the iOS ’86 theme installed, you’ll will need to jailbreak you iPhone or iPod touch with Absinthe for iPhone 4S and jailbreak with Redsnow for the rest of the iDevices on iOS 5
Step 1. Open Cydia, and add http://repo.ithemes.it to your list of sources (you’ll notice that Cydia warns you that the repo has been reported for redistributing copyrighted works. Normally these types of repos are not recommended but this was the only place we could find the theme).
Step 2. Search in Cydia for ‘iOS 86′ and install it.
Step 3. After that, you’ll need to activate the theme in Winterboard and re-spring your device.
Step 4. Finally, it’s not mandatory, but we recommend you download and apply this white wallpaper and set it to your homescreen.
