Top 10 Best Cydia Sources 2014

What are cydia repositories you may ask. A repo is a virtual storage where you can find apps, tweaks, themes and many more. But what is the purpose of a cydia source. For once you will not find in App Store tweaks, themes because Apple will not allow such packages to be hosted and the only way you can install these kind of packages is to jailbreak using the appropriate jailbreak tool for you iDevice and iOS version.
Maybe if I present some of the most used packages from a list of ten most used cydia sources you will get the idea.

BigBoss
