When you have minor software issues like an app crashing, restarting your iPhone would usually fix it. But Apple doesn't provide an official "Restart" or "Reboot" option (unless you count this bold text hack), so we typically have to power our devices off and on in these scenarios. Thankfully, there's a great Cydia tweak that lets you "respring" your device, which is even faster than restarting.
It couldn't be any easier to remove apps from your iPhone — simply do a long-press on the app's icon, then tap on the delete button once it pops up. However, when it comes to removing unwanted tweaks and apps from a jailbroken iPhone, the process is often a little more involved.
Unlike the iOS App Store, which is a one-stop shop that lets you search for and instantly download apps on your iPhone, jailbreak apps found within Cydia are far more fragmented and not as easy to source. In fact, Cydia only comes stock with a fraction of the apps and tweaks that are available on its official Apple counterpart. That's where Cydia repositories come in.
