Yesterday, we brought you a full review of a hot new jailbreak tweak called Mirmir (formerly Mimir). This is a new tweak that allows you to have true side-by-side windowed multitasking on jailbroken iPhones and iPads running iOS 8.3 or iOS 8.4.
If you'd like to try Mirmir, you can get it today for $3.99 on Cydia's BigBoss repo. Watch our video review in this post if you'd like more info before you buy.
