WHAT OPERATING SYSTEM DOES THE IPHONE USE?
iPhone uses OS X, the world’s most advanced operating system. Which means you have access to the best-ever software on a handheld device, including rich HTML email, full-featured web browsing, and favorite applications including Address Book and Calendar. iPhone is also fully multi-tasking, so you can read a web page while downloading your email in the background.

WHAT IS A PROXIMITY SENSOR?
When you lift iPhone to your ear, the proximity sensor immediately turns off the display to save power and prevent inadvertent touches until iPhone is moved away. Another power-saving feature is the ambient light sensor. This intelligent sensor automatically adjusts the display’s brightness to the appropriate level for the current ambient light.

WHAT IS VISUAL VOICEMAIL?
Visual Voicemail allows you to go directly to any of your messages without listening to the prior messages. So you can quickly select the messages that are most important to you.

IS UNLOCKING THE IPHONE ILLEGAL?
No. In fact, there is a strong argument suggesting that the locking of phones by mobile networks should be illegal, as it restricts choice and freedom. It''''''''''''''''s your phone and so you should be free to chose which SIM card to use with it. You would never get a car manufacturer saying you can only fill up your petrol with Shell!

IS UNLOCKING THE SAME AS UNBLOCKING?
No. A blocked phone is one which has been reported lost or stolen and which the network barred to discourage phone crime. Removing this block is illegal, punishable by a 5-year prison term and rightly so.

WILL I BE ABLE TO USE MY IPHONE ON ANY OTHER NETWORK?
After unlocking the iPhone, you can use your phone on any network that uses a GSM service (most networks in most countries worldwide).

WILL ALL THE SAME FEATURES WORK?
Except for Visual Voice mail (which is an exclusive AT&T & O2 feature), all features currently available on locked phones are available on unlocked phones. Some applications such as YouTube may require some manual configuration.

CAN THE PHONE BE LOCKED AGAIN ONCE IT IS UNLOCKED?
Our advice on this is simple - DO NOT ACCEPT THE SOFTWARE UPDATES! There is a risk that if you update the software, Apple will re-lock the phone or try to damage the software. The way to counter this is to not accept the iphone updates - remember, they are optional to install. If in doubt, get back to us at fone doctors.
