Is there an app I can use to keep track of everything done on my iPhone?

I let someone use my phone the other day and I asked them not to snoop around. I wanted to know if there was a way to see what they were up to while useing it. I know I can get apps and stuff to lock my pictures and stuff up. But that doesn't allow me to see everything that was going on at the time.

How to turn on iPhone 4 without lock button?

My lock button has been broken for a couple of months. Yesterday my phone turned itself off and was still on full charge. As it was still charged and it's off it won't run out of battery so I can't wait for it to die then plug it in. I've also tried leaving it charging overnight and plugging it into the computer and neither have worked. Can anyone help me please.

IPhone charging but not coming on?

I have the most important work trial of my life today. I need to leave the house in about one and a half hours. I'm going to be there all day and I need my phone no matter what to arrange lifts and find my way around. It has been on charge all night, but I just woke up to find that it is still on 1%. I restarted the phone and it went straight to the black screen with the red battery picture and the charging symbol. But that was fifteen minutes ago and since then it still hasn't come on. I don't know what to do. It is like it is accepting the charger but not charging. Any advice?
