As you all know, Cydia is a valuable source for amazing and useful apps and tweaks. The Apple Store can provide you all those apps but you will have to pay for each one of them. On the other hand, we have the help of Cydia to download all those great Cydia apps and tweaks for free. This is the best part with Cydia. It offers us the opportunity to maximize performance and power without charging any money. Cydia only comes when you jailbreak your device. Therefore, if you want to have Cydia on your side, you need to jailbreak your device now. Since this process is free and simple, you should start it now. After you have Cydia on your device, you can start exploring it at its full capacity. Once you start Cydia for the first time, you need to register as users and start adding some of the best Cydia sources. This means that you have to add a database where you can search for apps and tweaks.
At the beginning, you will have some default sources added. If you consider that these apps are enough for you, you may remain in this position. On the other hand, if this thing does not please you, you can easily add other sources. I want to show some valuable Cydia sources to help you. In the first instance, there is the SinFul phone repo. This is a great source for amazing free Cydia tweaks because it is a host of amazing cracked paid apps. If you have the possibility to download them free, why not take advantage of it?
In the second place, I want to place the iModZone where you can find other great apps. If you do not find a certain app on one source, you can easily try on a different one. In the third place, there is the apt.xellize repo. This source hosts only payable apps but when you really need a certain tweak, I am sure that you will send several bucks on it.
These are only some important repos but there are the standard repos, which come along with Cydia that are also very useful and valuable. When you find a different source, add it to your Cydia portfolio and then share it with others.
