Cydia is a well know word in the jailbreak community and a must have for every iDevice user that jailbreaks. If you are new to these terminologies don’t despair. We say iDevice to every mobile device that has the Apple logo, jailbreak the procedure in which you remove all the limitations imposed by the manufacturer. So this brings us to the last word Cydia. Well consider this, people who know about Cydia this is the reason that they jailbreak. Why? Well Cydia is the number one third-party distribution platform for software that runs on iOS. It is developed by Jay Freeman alias saurik.
If you want to get it you can easily download Cydia and install it via a jailbreak tool or separately if the device is already jailbroken. There are some pretty interesting things in Cydia beside applications, like tweaks, for this I suggest you should check out some cydia sources. But the packages that popular in the community are WinterBoard used to change the interface of your iDevice, SBSettings an easy to access panel to some important functions and information, Barrel animates the transitions between the pages in your Springboard, Active helps you assign new gestures to ease the use of your iDevice. So clearly there are some benefits if you install Cydia.
