You can change your boot up sound on the iPhone and iPad. Some users will find it cool as hearing the same booting up tune can get you bored really quickly. There is a jailbreak tweak for this and it works on iOS 7 devices that have been jailbroken with Evasi0n7 untethered program.
The new sound can mean new beginnings for you. Why won’t you give it a try? The jailbroken smartphone and tablet means a lot of new boundaries. You can change your animations, color of the keyboard, adjust Messages app, add new features, including the sounds you hear each time you reboot.
BootSound is the tweak designed for interesting booting up. This Cydia tweak brings the tune Mac users hear when they start up their machine. This is the sound you can get for your iPhone or iPad.
Sadly, the jailbreak app comes with this sound only and can’t offer you to choose your own tunes for starting up the handset.
