Jailbreaking is all about having the freedom to alter and change the way the native iOS device looks and behaves and themes are one way to do this. WinterBoard was the main application used to execute themes but this is all about to change thanks to a new application called DreamBoard. DreamBoard is an advanced theming platform which takes control of the device's SpringBoard and lets user take almost complete control over placing widgets and apps, removing the limitations which existed through traditional theme methods.
DreamBoard has plenty of great options with great themes and aesthetic modifications which are compatible with DreamBoard are available through Cydia. These include the Metro DreamBoard theme which was the first complete Windows Phone/Windows 8 inspired theme. This theme consists of twenty one tiles with two animated one and there is no external setup required. OS7 is another DreamBoard compatible plug and play theme which benefits from the auto creation of home page tiles as well as an alphabetical list of installed applications. Metro 8 is another Windows Phone theme for DreamBoard which comes with a basic theme setup and is a great alternative advanced theme for those looking for more.
These three themes are just some of what is available for DreamBoard and there are plenty more available in Cydia. In order to use any of these themes you do need to have a jailbroken iPhone or iPad.
