What is Cydia? This question is quite popular among new users and iPhone owners. Beside Cydia, we can also hear about jailbreaking and unlocking. Actually, jailbreaking and Cydia are pretty related in a way or another. The only way to get Cydia is if you jailbreak your device. After the first use, you will understand what Cydia is.
In a few words, I want to tell you that Cydia download is an independent third party Store that hosts impressive and amazing Cydia apps, tweaks or programs. Users are able to download useful apps free of charge or with a lower cost. I will also want to mention several things related to apps, tweaks, sources or repos. These things are connected also with Cydia. So, when you first launch Cydia, you cannot tell too much. You will see five tabs displayed in the home page and soon, Cydia will ask you to identify yourself as an administrator. After this, Cydia needs to initialize its packages. This will last only a couple of seconds. Then, Cydia is ready to be used. Therefore, Cydia apps and tweaks are useful apps that can be found, downloaded and installed from Cydia download. However, each one of these apps is hosted in various sources. These sources act as platform for all those great apps, tweaks and programs. You have some default sources at the beginning, but you can easily add new ones to use.
Cydia represents the only way through which users are able to customize and change appearance, themes and other important details regarding their devices. However, to make things clear, Cydia does not offer only free tweaks and apps; here, you can also find paid apps and packages. As a relief, their prices are not that high.
