Few months ago, I went on trip and my phone disappeared for few days. Since I wasn't using it I didn't think any of it. Anyways to make this story short. Since then my phone has been somewhat slow and acting up a little. I know I can restore the phone to eliminate any bug, but I want to know if there is any way that can confirm that someone else is having access to the info stored in my iPhone. I known I should have been more careful. I thank you a for your help in advance!
