I think I made a rather stupid mistake
My iPhone battery was getting old, so I went to a local repair shop to get it replaced. It's not an Apple Store, just a couple of guys who fix PCs and do odd jobs like that.
They agreed, and said I could come back in an hour. When I came back, they said the phone was ready but asked me to provide my PIN. I don't know why this was necessary, but stupidly, I gave it to one of the guys. He turned on the phone, then unplugged it and gave it to me.
I now realise that in the time I had been gone they could have taken an entire image of my phone onto their PCs. They now have the PIN too, so is this a massive security risk for me?
I have changed all the passwords to all the emails, facebook, and Apple ID. No idea what else could I do? I feel really stupid for giving up the password to them.
What could they do with the the data they (might) have? What is the possible damage? Any steps I could take to minimise any possible harm?
