Apple keeps a tight grip on your wallet through iTunes, which is always ready to wipe content from your iPhone, iPod Touch or iPad. But many people aren’t aware that iTunes allows you to share games, apps, music and videos across devices, so long as they’re all linked through one account.
iTunes Account – Share iPhone Apps and Other Content
Despite Apple’s iron hand when it comes to what you can and can not work on your iPhone, iPod Touch or via iTunes iPad there is a feature of the multimedia gateway, the surprisingly liberal’s burden. All downloaded or purchased content to be synchronized to iTunes, and essentially shared, any number of devices – as long as they are all linked to the same iTunes account.
This allows you to share iPhone apps, games and other content. By signing have your computer into an iTunes account, you can purchase and download music, videos, TV shows, games and applications on the computer and then synchronize it with your iDevice. The same applies in the opposite direction, and acquired all the content directly on iPhone or iPod transmitted to the computer during the sync process.
You can also sync as many devices as you like with iTunes, and all its contents from the different iPhones, iPods, iPads and the computer down the line, without it will buy again replicated. This is especially useful for families whose members each have their own iPod, iPhone or other Apple device. Once buy, and share the goods.
Authorizing Computers
Although you can have as many devices on an iTunes account as you want, you can only have five computers at any one time.

In the “Store” menu on iTunes is an option “allow this computer.” After iTunes is installed, you should mark this option and in iTunes with the same account under which Apple will tell you how many computers are currently registered. If you decide to set up a separate iTunes account for this computer, you should “de-authorize” to this computer “option, then re-register with Apple for the new account.
Should a computer go bad, or without first de-registration be reformatted, but the only way to de-authorize all computers that iTunes account. Apple you can only do this once every 12 months, so caution is advised when the permit computers, so they do not get to hold a slot be used during rare.
Spending Money
A possible disadvantage of sharing is iTunes content on different devices and computers that someone can be related to the account to spend his money. There are no controls over who is to spend, or how much you spend. If there is a credit card linked to your iTunes account, the purchases will be automatically loaded onto the card.
Buying iTunes vouchers, instead of registering a credit card is an option to minimize this problem. All users can spend with a credit on the iTunes account without restriction, although the amount that can be spent is obviously limited to the available credit. After several users on the same account also increases the safety risk and the risk that the account information from people who are not destined to share the content could be detected.
Once someone has access to the account, they can access the profile, change all the details (such as the password) and spend any available money. Extra vigilance must be employed when sharing a iTunes account.
Summary
Sharing an iTunes account is a great way to avoid my salary more than once. It allows you to share iPhone apps and other content, and is all within the agreed terms and conditions of Apple, and is completely legal. Think of it than to buy a DVD, and all sit together to watch them. Any person on the sofa is not expected to share the DVD before visiting the family, buy, and that is the same principle, an iTunes account.
Just be sure you trust everyone who is brought into the account, and that your payment method is secure and agreed upon by everyone who’s sharing.
