Seriously. If you feel a burning need to be dominated and degraded by a pro, then you clearly need to own the newest iPhone:

Thousands of iPhone 6 users claim they have been left holding almost worthless phones because Apple’s latest operating system permanently disables the handset if it detects that a repair has been carried out by a non-Apple technician.

Relatively few people outside the tech world are aware of the so-called “error 53” problem, but if it happens to you you’ll know about it. And according to one specialist journalist, it “will kill your iPhone”.

The issue appears to affect handsets where the home button, which has touch ID fingerprint recognition built-in, has been repaired by a “non-official” company or individual. It has also reportedly affected customers whose phone has been damaged but who have been able to carry on using it without the need for a repair.

But the problem only comes to light when the latest version of Apple’s iPhone software, iOS 9, is installed. Indeed, the phone may have been working perfectly for weeks or months since a repair or being damaged.

After installation a growing number of people have watched in horror as their phone, which may well have cost them £500-plus, is rendered useless. Any photos or other data held on the handset is lost – and irretrievable.

Tech experts claim Apple knows all about the problem but has done nothing to warn users that their phone will be “bricked” (ie, rendered as technologically useful as a brick) if they install the iOS upgrade.

Freelance photographer and self-confessed Apple addict Antonio Olmos says this happened to his phone a few weeks ago after he upgraded his software. Olmos had previously had his handset repaired while on an assignment for the Guardian in Macedonia. “I was in the Balkans covering the refugee crisis in September when I dropped my phone. Because I desperately needed it for work I got it fixed at a local shop, as there are no Apple stores in Macedonia. They repaired the screen and home button, and it worked perfectly.”

He says he thought no more about it, until he was sent the standard notification by Apple inviting him to install the latest software. He accepted the upgrade, but within seconds the phone was displaying “error 53” and was, in effect, dead.

When Olmos, who says he has spent thousands of pounds on Apple products over the years, took it to an Apple store in London, staff told him there was nothing they could do, and that his phone was now junk. He had to pay £270 for a replacement and is furious.

“The whole thing is extraordinary. How can a company deliberately make their own products useless with an upgrade and not warn their own customers about it? Outside of the big industrialised nations, Apple stores are few and far between, and damaged phones can only be brought back to life by small third-party repairers.

It appears that Apple’s new motto is, “There is a sucker born every minute.”
