iOS 

The mobile operating system for Apple mobile products. Android and iOS are direct rivals. Personally, I believe Android is better for more advanced users, and iOS is for users who want a more simpleminded experience.

iOS is developed and maintained by Apple. It was created by Steve Jobs.

IOS 

Invisible Oji Syndrome - Caused by a false sense of importance and security given by Oji
Symptoms include; Vomiting, Erectile Dysfunction (Only Oji makes you hard), Random sensations of Oji on your skin (Worse than creepy crawlies), Random hallucinations of Oji, Death followed by resurrection by Oji (Rare)

If IOS is not cured within 7 days the patient will most likely experience seizures, shortly followed by death.
People who have died to IOS will be taken to the "Gokurakujyoudo"(極楽浄土) which is a place of salvation after death where the soul is cleansed by the Oji.

IOS is more common than you think. Oji is everywhere around us, the ground, the air, your mom. People around you may be suffering from IOS. Make sure to spread awareness. If you think you have IOS please call the Oji mutation control centre at [phone].

-Walter White: Gus Fring had been feeling Oji stroking his dick

-Jesse Pinkman: Oh yeah, Gus Fring has severe IOS.
