5. iTunes Is Your Favorite Place to Shop: How much are you spending on songs and apps every month? Does your iPhone have 10 screens of apps? We bet you can't wait for the folders feature in iPhone OS 4.0. There are no hard figures on this, but we're guessing $100 a month on average at the iTunes store is probably too much. Apple is also bringing its iAd mobile advertising platform in iPhone OS 4.0. The goal of iAd, says Apple CEO Steve Jobs, is to help developers make some money without raising the price of their apps. This should come as welcome news to iPhone addicts and their wallets.
6. You're Infatuated with Steve Jobs: Apple CEO Steve Jobs can be an industry unto himself. There are Steve Jobs plush dolls, Steve Jobs posters, "Steve Jobs for President" t-shirts, even instructions on making a Steve Jobs cheese head. Bonus points: You also have a warm spot for the "other" Steve, Apple co-founder Steve Wozniak. And, of course, you secretly rooted for him on Dancing with the Stars.
7. You Bought Multiple iPhone Cases: Let's be honest: Accessorizing your iPhone, as if it's a Barbie doll, is unhealthy behavior. There's an iPhone case for every occasion. And we're not just talking about women iPhone owners, either. If you spent $50 for an Otterbox Defender case, one of the toughest iPhone cases on the market, you probably fall into this category. The holster holds the iPhone in the vertical position, like a gun. The Otterbox Defender has often been called the "soldier's case." The black case and holster look pretty intimidating. We're guessing the exec with an Otterbox Defender for his iPhone also drives a Hummer to his downtown office, too.
8. You Can Outrun the Energizer (ENR) Bunny: If you need to change your battery in less than year, you're clearly an iPhone addict. Every time you go through a charge cycle on your iPhone, you'll permanently lose anywhere from 30 seconds to a minute of battery capacity. Typically, you'll get 250 to 500 charge cycles before a lithium ion battery has outlived its usefulness. Aaron Vronko, CEO of Raid Repair, which services broken iPods and iPhones and replaces worn-out batteries, says the battery-replacement demand curve starts with a 10-month-old iPhone. These customers are often heavy iPhone users who may have lost up to 30 percent of the original battery life, he says, and 70 percent of the remaining battery is not good enough for them. You can also go to educational website iFixit.com, buy a tool kit and replace the battery yourself.
9. You Name Your iPhone "My Precious": A Stanford survey caught a few students naming their iPhone and even patting it like a puppy. One out of four described the iPhone as an extension of their brain or body. iPhone addicts also tend to be loners, constantly staring into the device, even mesmerized by it. Stanford roommates living with an iPhone addict call themselves "iPhone widows." If you find yourself always alone, perhaps letting your hygiene go, and murmuring the words "My Precious" to your iPhone, then, well, you're more than just an iPhone addict. You've got serious problems, buddy.
