With Apple's new handsets going on sale Friday, experts are warning customers against buying fake and knock-off iPhones by highlighting some of the techniques criminals use to dupe them.

The Counterfeit Report explains what to look for when buying an Apple product, including the Designed by Apple in California stamp, and how to check the product is an official design using Apple's services and warranty checker.

Fake iPhones and chargers have recently been linked with a spate of accidents as well as a death in China, where counterfeit Apple products are rife.

According to the Counterfeit Report, customers who think they have a fake handset should compare it with a friend's iPhone.

HOW TO SPOT A FAKE IPHONE

Official handsets will come with a serial number printed on the rear of the device.

This serial number can be entered into Apple's Service and Support Checker to confirm a phone's authenticity.

An official box is not an indication of an official phone - boxes can be recycled.

Check for the Designed by Apple in California stamp.

Only buy from official retailers.

According to the Counterfeit Report : 'When you buy from a internet site, and not from an authentic Apple dealer, you risk buying a cheap Chinese knockoff.

'If you think you have a fake, just compare it to your friend's iPhone.

'The processor speed, touchscreen and feel should be identical.'

The site continues that an authentic-looking iPhone box is 'not an indication of an authentic Apple iPhone 4' and explains some counterfeiters will package fake phones in official packaging to convince buyers of its authenticity. 

Elsewhere, the site states that each iPhone has a unique serial number.

To check whether a serial number has been forged, repeated, or if an old box with an old serial number has been used with the knock-off handset, customers can type the number into Apple's support site.

The Service and Support Checker will confirm if a handset is the real-deal or not. 

A serial number is found on the rear of the phone's box, on an official receipt, or on the rear of the device.

Earlier this year, Apple in China posted instructions on how to tell an official power adapter from a fake one, after a number of iPhone owners claimed to have been electrocuted by their handsets.

The page showed images of chargers for each Apple device, including the iPhone 5 and the iPad 2, with the official, relevant safety notices underneath.

The Counterfeit Report explains how to spot a fake iPhone by checking the handset's serial number, and looking for the Designed by Apple in California stamp printed on the back of the phone.

As well as recycling official packaging, counterfeiters will also recycle official serial numbers. These Apple iPhone boxes pictured appear to be the real-deal but the IMEI numbers, highlighted, are repeated

The electrocutions took place in the Chinese cities of Beijing and Xinjian, putting one man into a coma and killing another woman.

The site reads: 'This overview will help you identify genuine Apple USB power adapter.

'When you need to charge the iPhone or iPad, we recommend that you use the standard USB power adapter and USB cable.'

All iPhone and iPads are sold with official Apple chargers, although fake replacements can be bought online.

The Counterfeit Report also explains how to spot fake USB chargers, Xbox games, Sony flash drives and Nikon camera batteries, among other electronics.

It additionally lets users report fake websites and products.

Although the site explains how to spot a fake iPhone 4, the techniques counterfeiters use are the same across models and apply to more recent handsets, too.

How to spot a fake Iphone.. Step 1. Look at it

Just don't upgrade iPhone C or S will have no problem, hated those Chinese knock off. Think twice before buying anything from China such as sauce, god know what they really put in there.

You have nothing left, Apple. You did do a good job with the first version of it. Pretty damn good. But you've been releasing the same thing for several years now. And you can take iTunes and stick it up your behind. I'll give you one thing though. You'll have fans lined up to buy the next thing you put out. Your marketing department deserves a raise.

I wouldn't have an Iphone give me let alone buy one

''Earlier this year, Apple in China posted instructions on how to tell an official power adapter from a fake one, after a number of iPhone owners claimed to have been electrocuted by their handsets.''complained after they had been electrocuted?????????

There was a company advertising under the name of Wufada.com in China, purporting to sell MacBook Pro, MacBookAir, and iPhones online.

Seriously, as soon as you open it you'll be able to tell the difference

I have a fake Iphone, I brought it knowing it was fake one of the cheapest phones available. I can't rate it enough, it runs on andriod so I call it my Idroid. For 80 including everyday and 2 batteries I'm not going to complain.Unless I tell people you can't tell the difference!!

Who has the resources to copy such a sophisticated piece of technology? I mean, this is not a knock-off of a handbag or something simple like that.

Fear the knock-offs! You're in danger of getting a good price for once.....
