IPhone Disabled? (iPhone 5)?

My phones screen says "iPhone Disabled" but I didn't enter any wrong pass codes and no one touched it

What does this mean? How did it get like this? How can I fix it to get back into my phone without erasing any data?

It won't let me in but all that it does, is let me dial an emergency number and thats about it. It won't let me in at all.

Try and find a software to unlock it. There are many softwares to do such things
