Some people tend to prefer the risk of damaging their naked iPhones over slapping a protective case onto the device. The reason? Cases usually diminish the natural elegance of the bare iPhone and instead replace it with generic polycarbonate or silicone (in most situations). However, for those users who are willing to come halfway rather than possibly damaging their phones without any protector or using a case, there are numerous other solutions currently available. Part of the company's Original Series, Mujjo's Sleeve for the iPhone 5 ($45) is a top contender despite its rather high pricing.
While the usage of caps lock is generally reserved for comment trolls and confused old folks, it can be very useful when used responsibly. The iPhone does have a caps lock mode built in, but it's disabled by default. To enable it, go to Settings > General > Keyboard and turn on "Enable Caps Lock." Now whenever you need to type in all caps, simply double-tap the shift key to engage caps lock.
Additionally, you can also use this method to enable CHOCK LOCK MODE OK.
