1 Cydia App/Tweak/Theme you can't live without

After years of jailbreaking iOS devices, I pretty much know Cydia inside and out now. I don't think a day goes by without me browsing through what's new in my repos. I love adding a clever tweak to my phone and am on a constant quest for the perfect theme.

If I had to choose one thing from Cydia I couldn't live without, it would have to be SBSettings.

What's yours?
