Those with jailbroken devices running iOS 8.3 or iOS 8.4 can now unjailbreak without updating or restoring. This means that the iPhone, iPad or iPod touch is returned to stock iOS without changing the iOS version.
One of the popular iOS system modifications on Cydia is known as Cydget. Developed by Jay Freeman (saurik), Cydget is available free for jailbroken devices on the Cydia/Telesphoreo repository.
There are currently 93 add-ons for Cydget available in the section Cydia -> Sources -> All Sources -> Addons (Cydget).
If you haven't installed Cydia's Substrate Safe Mode (which you should definitely do) you may find yourself with a tweak that constantly crashes or puts you in a boot loop. Here is how you can manually enter safe mode:
1. Reboot (unless your phone already is) by holding down the top button until the "Slide to power off" message appears.
You can change the carrier logo on an iPhone by downloading the Cydia tweak Zeppelin. It's available for free in the ModMyi repo or just search "Zeppelin". The tweak works with all jailbroken devices.
Once installed go to Settings --> Zeppelin --> Theme and select the icon that you would like to replace your carrier logo with. Zeppelin comes with a few pre-installed icons (e.g. Apple logo, Pac-Man) to get you started, but there of plenty of Zeppelin Addons available in Cydia.
Looking for local weather and a forecast to be instantly available on your LockInfo screen like the example below? Adding these tweaks to the default LockInfo screen can be done in a few easy steps. To begin, make sure your iPhone is jailbroken and you have successfully installed the LockInfo tweak. This Cydia tweak provides similar functions to the iOS 5 Notification Center.
