Security experts have warned about a new email scam that uses the iPhone '5G' as bait.

Spam emails are circulating that try to tempt you to unwittingly install a Trojan on your Windows PC by promising you more information about the next-generation iPhone.

However, the scammers seemingly haven't done their homework, as the subject line attests: "Finally. The amazing iPhone 5. Now available in black edition." The email appears to be sent by the address [email protected]

Despite the fact that Apple hasn't announced a fifth-generation iPhone yet - and is unlikely to do so at WWDC today - the scammers seem to think that we'll be taken in by their mock-up of the 'new' iPhone that comes complete with a slide-out Qwerty keyboard.

"Introducing the iPhone that lets you do more than ever. And do it amazingly faster. Launch and switch between applications quickly. Bigger display, transparent mode, better cloud integration. Shoot, edit, and share video like never before. Slimmer, faster and sleeker. Discover many more features that make iPhone 5G S the best iPhone yet," the email reads.

Graham Cluley of security firm Sophos said: "Of course, the images of the iPhone 5 with a built-in hardware keyboard are just some fanboy's dream."

Clicking on any of the links in the email could have dire consequences for Windows users, though the Mac OS and iOS platforms are not targeted, given the nature of the bait.

"Ironically, this spammed-out malware attack doesn't infect iPhone or even Apple Mac users - the Trojan only infects the Windows operating system," Cluley said.
