My reasons for jailbreaking:
- RecordPause (pause a video while recording)
- Adblocker 2 (Ad-blocking done the right way - the built in blocker is just as badly implemented as 3rd party keyboards)
- Apex 2 (much better intepretation of folders)
- Aria 2 (being able to choose the tabs on the bottom in Music.app eg. Genres, Interprets, Albums - NO more annoying Apple Music!)
- Ayeris (App icons the way they should be - perfectly designed)
- Canopy (hold on the Tab thumbnail in Safari to quickly open a new tab)
- Cloaky (hide annoying badges like "Activate Wi-Fi or disable airplane mode now")
- Cou (change "slide to answer" knob in Phone.app to buttons)
- Flash (show a flash icon on lockscreen when it is dark automatically)
- GrabberTime (handy clock on grabber of Notification Center)
- Icon Renamer (Rename the icons on the Home Screen)
- NCifNeeded (open notification center to the logical section: if there are no notifications it will open the other tab instead)
- OneTapClear (one tap on the X in notification center dismisses everything)
- Priority Hub (truly my favorite: amazing way of sorting incoming notifications on the lockscreen)
- SwipeSelection (use the keyboard as a touchpad - just like on the 6s, just for older devices)
- Youtube Special version (in Youtube.app: background audio, audio while screen off, download videos)
- Zeppelin (hide the carriert text in the top bar)
- StatusVol X (show the volume indictator subtly in the top bar)
- Downgrading your poor old 4s on iOS 9 to iOS 6. It will feel like a 6s speedwise!
...
and so much more.
I encourage everybody to try it out, it wil supercharge the way you use your phone! Feel free to hit the thumbs up button if there was anything in the list that made you want a jailbreak.
EDIT: here are some smaller tweaks if you are interested:
- Universal Mute (the vibration switcher mutes ALL sounds, not just notifications)
- SpotlightBeGone (disable the left-handed spotlight in iOS 9 (useless, I think))
- NoLowPowerAlert (hide low power alerts)
- NoSlowAnimations (just increase the animation speed a little bit. If you then use a phone without this tweak it will feel like a snail)
- ColorBadges (color the badges on app icons to match the color of the icon)
- ASUpdateHider (hide updates in the App Store. Perfect if you decide not to update a certain app and don't want to see it in the updates list)
