Arguably the most exciting feature from Apple's iPhone 6s announcement earlier in the year was 3D Touch, which gives you the ability to access more options for apps straight from the home screen. 3D Touch is only available on iPhone 6s and 6s Plus models because it works via their new Force Touch technology.. until now.
With the Jailbreak tweak 'Forcy' you can use all the 3D Touch features on any model of iPhone you like.
Once installed and activated, a small hold on an app will give you all the options that you would get with an iPhone 6s with 3D Touch. If you ever want to delete an app, a small hold and a flick up will display jiggle mode, where you can get rid of any apps you like.
You can download Forcy from the BigBoss repo for free.
If you ever experience any lag with Forcy, download a tweak called '3DNoLag' and it will remove any lag.
To add more 3D Touch options to apps that don't usually have them such as Weather, Spotify, and Settings, you can download a tweak called 'Shortcuts'. This is available from the BigBoss repo for $0.99.
