Does updating your iphone relock it
All jailbreaks are reversible, but what most users don’t know is that you can easily unjailbreak an i Phone by using the Restore functionality within i Tunes, and then you can restore your apps, contacts, and i Phone customization to the device as well.
This process is the same to undo a jailbreak on an i Phone, i Pad, i Pod touch, or even an Apple TV.
Enter Nexus 5 as the model, and refer to the build number you jotted down in Step 2 for the Android Build.
As you probably remember, the process of unlocking your Nexus 5 deletes all of your phone's apps and data.
To add songs one can simply drag them from a folder onto the Library portion of the side bar in i Tunes.
