By jailbreaking their devices, most users usually know what they expose themselves to. When breaking the walls Apple has constructed to protect their security and privacy, jailbreakers put their fate in the hands of a handful of people. If done with basic principles in mind, jailbreaking can be very safe. I, for example, have been jailbreaking every iOS device I have owned since 2008, and I have yet to encounter any issue whatsoever.

Being cautious starts by being aware of what you install on your jailbroken device. Limiting yourself to the default repositories is good practice, as these repos do an outstanding job at analyzing jailbreak apps and tweaks before making them available for download, ensuring that the final user is as safe as possible.

But there is always that slight chance that a malicious tweak might have gone through the cracks and made its way into Cydia for millions of potential users to download. Nothing is 100% safe, but safety measures can be put in place to ensure the highest level of security. This is the job of repo maintainers.

We have talked to representatives of the two largest default repositories on Cydia to ask how they ensure the safety of their users. In a two-part series, we will publish their answers, starting today with Optimo, repo maintainer for BigBoss. Tomorrow, we will publish answers from Kyle Matthews of ModMyi.
