The shocking revelation came few hours
ago that Apple, the owners of iOS
devices will render your phone useless
if you ever upgrade to the latest version
of iOS which is iOS 9.0
But why this decision? What is the
reason? My people, the reason for this is
very funny but interesting. iPhone
producers are over protective to the
extend of now restricting iPhone users
from repairing their damaged device by
a third party technician and if at all you
have done it already, then you should
not smell or go near the latest iOS 9
update. According to Apple, your
device will be ruined if you try it.
There is an error 53 that appears after
the update and that is the main danger.
But come to think of it, apple might be
afraid of intruders acting as third party
technicians and installing some bots and
Malware on your device. So in another
sense, its a good security measure but
they are really really over protective and
places too much restriction on their
devices.
