Someone has recently hacked into my iPhone. A couple weeks ago, I started experiencing Apps being moved around every couple days. (It's not me, I am very careful about moving my apps). Then one day, I found that someone had created a folder on my iPhone. Now I started getting odd text messages which I've had to block. This is my first smart phone and did not know what to do to prevent hacking. I set up a security passcode, but I am worried that this is not enough and I wonder if the hacker accessed additional information from my cellphone. Oh yes, now I've started receiving IMs from the same person who was sending me text messages. What can I do to prevent this hacker and other hackers from accessing my smart phone and ultimately my pc? Should I change my cellphone number? Not knowing what they accessed on my phone should I change all my passwords? What else should I do?
