When you buy a phone, the last thing you do is mess with its settings. At least that's what I try to avoid, believing that if I tinker with the phone's original settings, I'll disrupt the magic and balance of the new device.
By now, you probably feel like you know the drill. Every year Apple prepares the release of the new iPhone, offering mostly minor tweaks to their popular device. Bigger screen, storage space, no headphone jack. That type of thing.
