Almost immediately after buying my first iPhone in 2009, I became hooked on jailbreaking. Despite the fact that my iPhone 3GS met all of my mobile computing needs, I couldn't resist the temptation to tweak my user experience: tethering my computer on the go, messing with the color and style of my onscreen keyboard–you name it. If it was available for download via Cydia app, I gave it a spin. Some apps and hacks were worth paying for. Many weren't. I never dabbled in pirated apps, but I could have! That's what was so wonderful about Cydia: it offered the possibility of wandering off the path of what was normally a walled garden.
Sadly, after years of service to the homebrew and jailbreaking community, Cydia is shuttering its store.
From Engadget:
Service creator Jay Freeman (aka Saurik) has shut down the Cydia Store citing a combination of costs and security issues. It "loses [him] money" and, when there were multiple staffers, cost him a significant chunk of his "sanity." And while Freeman had already planned to close the store by the end of 2018, he bumped it up a week after learning of a security hole that let let someone buy apps through your account if you were logged in and browsing untrusted app repositories.
The good news is that you’ll still be able to gain access to apps previously purchased in the Cydia store – at least for the time being. As sad as it is to see Cydia winding down, this isn’t the end of the road for jailbreaking. Those looking to hack their iOS device will still have options. The whole point of jailbreaking is that no one company is able to hold sway over what you do with the hardware you own. Other digital tinkerers will no doubt pick up Saurik's torch.
