Do you hate that annoying coworker who typically shows around his sparkly new iPhone? Does your boyfriend or girlfriend or brother usually take and mess with it? Would you want to get some revenge?
If you’re able to get hold of his iPhone while he or she is gone for only a few minutes, then you are one step ahead. In the case of a coworker, wait until he or she is away for a conference or is gone to the restroom and left his or her phone on the desk. This might take a lot of meticulous planning and just waiting around, but it will likely be well worth your time and effort.
In the case of siblings this should actually be a lot less difficult because you most likely are living with them.
To begin with you can actually modify the display language into a foreign language such as Japanese. Simply go to Settings – > General – > International then Language.
Yet another amusing gag you could try is chaning the order of their applications. Just press and hold any icon until they all are constantly moving, and then simply move them around, even going to other screens. For anybody who is upgraded to the most current iOS update, try organizing them in a confusing combination of folders. You can do this by dragging apps over each other. The phone should allow you to relabel the categories or folder when you see the inside of one.
Obviously, there is a well-known background modifying trick. With the most recent version of iOS (4.0 and above on iPhone), you’ll be able to change the background. If you can get a really hilarious (or even offensive) photograph, then that should do just fine. Simply find it in Safari, press and hold the photo, and choose Save Image. After that, go to the Settings — >Wallpaper and choose the image you took.
Last of all, a totally wonderful prank is displaying a fake screenshot of their background (with apps and all) and then locking the device. Once the victim unlocks their phone, they will be puzzled as to why their apps aren’t working. The downside to this prank is that whenever a user taps, usually some bar will get displayed, so the trick will lose its magic pretty quickly.
You’re lucky though: there are some apps that solve this challenge and even provide all kinds of other wonderful gags and tricks.
