Hi to all "companions in misery",
My iPhone 4S (5.1.1) and I just got back from seeing a total wiz & pro who runs a business fixing mobile devices, specialising on Apple products (usually he only does B2B).
He checked my phone (have the same problem as everyone here & have already posted in this forum about it some days ago) – he CONFIRMED it's a VIRUS that affects the OS (probably imported by apps, but installed itself directly in the OS).
Upgrading the device to the latest OS will fix it, but for all of us, who have quasi-lost their contacts and don't have a backup on computer or iCloud, those contacts can only be retrieved by a wiz/pro/geek.
On my phone too ALL names still appear in the "left-swipe" search – apparently, they're stored in the cache.
The guy said he would be able to retrieve them and that this also wouldn't affect my existing data (messages, photos, etc).
The only reason I didn't leave my phone with him right away is that I need to find a replacement phone for the couple of days it will be in repair...
Fingers crossed!
Also, I personally strongly ADVISE AGAINST buying so-called "data recovery software" online, even though it might be recommended in seemingly(!) trustworthy blogs etc - it won't work and you'll probably never see your money again. Trust me on this one, I learned the hard way...
PS: For decades, Apple has taken pride in not being vulnerable to viruses, trojans etc – so I'm guessing it won't be likely for them to admit that they are; they'll just keep "quietly" releasing OS updates resolving current / new issues.
Had they not effed up the whole Google / Apple maps, I would have probably updated my system, but in that case was reluctant to...
