First things first, what is iMIUI? Well from what I understand, MIUI is an Android ROM, built by the folks over at Xiaomi Tech. And iMIUI is a large-scale iOS port of that ROM, wrapped up in the form of a WinterBoard theme.
Perhaps more impressive, though, are the little touches. Blue accents have been replaced by Orange ones. And both radio buttons and toggles seem a bit more soft around the edges. I must say, the level of detail here is striking.
But above all else, iMIUI is just a really good-looking theme. The icons, which are the most important part of a theme, look excellent. They’re crisp, they’re understated, and very well designed. And the same goes for the various UI tweaks.
To install the theme, you’ll have to add http://cydia.myrepospace.com/imiui/ to your Cydia sources by tapping Manage > Sources > Edit > Add. It’s iOS 6 and iPhone 5-friendly, but at the moment there’s no iPad version available.
