Thanks Marilyn your quick reply
Sorry I mean everywhere in iPF forum whole team mentions "we not Support or help in piracy ", but Cydia also give pirated apps. So, is it not piracy ( sorry my English not good).
My another question is "Is it possible to downgrade iPad from 6.1.3 to 6.1.2 ? "
Thanks in advance
To get the first part out of the way - no, it's not possible to downgrade to iOS 6.1.2. In fact, it's not possible to downgrade to any version of iOS 6. Sorry, but your only choices are to stay where you are or upgrade to iOS 7.
Now, about Cydia and piracy.
Cydia is merely a place where people can register (for lack of a better word) their web sites where people can then list all the packages they have for downloading (whether free or paid). When you jail break, by default you install Cydia. It comes with default repositories of sites that have been vetted to ensure they contain no piracy materials.
The problem starts when people steal games and such and offer them to the public. As Cydia does not control who can link to piracy sites, anyone can type in a piracy repository at Cydia and then be directed to a site where they can steal games (and other apps) to their heart's content.
As Cydia is the middleman, this behavior cannot be stopped. However, that still does not make it legal or ethical. An individual still has to deliberately type in and go to the piracy sites that offer stolen games and apps; it is not available by default when you first jail break.
So, it's not Cydia offering pirated apps, it's the pirate deliberately inputting sites/repositories to go steal apps. It's a distinction yes, but blaming Cydia for piracy is akin to blaming Google's search site for allowing people to find illegal and immoral stuff.
Bottom line is that we don't support piracy here and neither does the owner of Cydia. If someone chooses to be morally corrupt and deliberately use Cydia to input repositories so he or she can steal apps, no one can stop them. But we don't have to deal with them.
I hope this clarifies for you. Do let me know if you need more information.
