Why is my iPhone 4 unlocking itself?

About two months ago I bough a new iPhone 4. Recently, it has been unlocking itself (I do not have a passcode) The phone can be placed in a bag, locked with the screed dark, and then pulled back out a while later for the screen to be unlocked and the apps showing (I do not have my phone on a lock setting; it is unlocked until you manually do it yourself.) it has also been unlocked during the night; I've woken up, knowing I locked it the night before, to flip it over in the morning to see the home page or a particular app open.
Any reason why it could be doing this?

Will Apple know if I took my iPhone apart?

I want to only take the screen off but nothing else. I just want to look at the LCI. Will Apple find out that I opened it? I also ordered a kit that gives you the correct tools to open it.

Is she shy or not interested? She never had a bf?

i'm 29, investment banker, ivy league background, she is 20 in undergard school.

when i first met her she was super shy, although she is a social butterfly. She told her aunt, who married my uncle, that she thought i was super cute and loved my personality. Eventually she opened up and gave me her number. We chatted, flirted, hung out and she enjoyed my personality.

we did this for 5 weeks, we would talk everyday, and then she didn't respond to me, i have no clue why, it was a complete 180. I tried to call her to see what's up but no answer, so i texted her and said if she is not interested in me, that is ok and i would move on with time. But that if she gave me a chance i would support her dreams and make her my queen. When i was younger i came off desperate to women, but now i'm a very wealthy guy and personally, i don't mind if i look desperate for a woman. And even the women from my past are looking for an excuse to "hang out" again but i'm over them, but i think they are just upset they missed out. I just want genuine love.

the things is she didn't respond to that either and i know she saw my text since the app said so on my iphone, i can deal with rejection but i rather here it from her rather than her not telling me.
