How to find iphone serial number? Broken and not backed up?

Hi so I know that apple will replace your iphone if it is damaged but you need the serial number… I have the physical phone but it is so damaged that it will no longer turn on. I went into itunes and checked under preferences and devices but my phone was not there so it was not backed up anymore, due to the fact that i lost my computer and all itunes information that i had. Is there any other way I can find the serial number? Any help would be great thanks.

Iphone 5 activation lock email?

Ok i have a problem. Firstly my iphone is not stolen. I had it and it was working and everything. I planned to sell it but knowingly to me about this activation lock feature i just created basically a junk apple id to sell with the iphone so i didn't have to give them my apple account on the spot. I just filled in all the stuff with garbage cuz i didn't know it would totally lock the phone like this. I sold the phone a few months ago and the person has been wanting to install apps but couldn't cuz the junk account is on there. I had to refund cuz i couldn't remember the info and password. I think if i can know which email i used to create it i can remember the password or at least put myself back into the mindset i was in. Cuz i put in random info for the security questions i won't be able to guess it to retrieve it. I believe i put in my email address as the backup account but i can't get to the forgot password without the account id and i can't get to the account id without the security questions.

Is there ANY way to find out which email address the iphone is activation locked to without the security questions or backup email address, basically without the iforgot thing?

How to turn off calling on iPhone 4? (read description)?

I'm going to DC for school and we "can't bring our cell phones." The only way we'd be able to bring one is saying that you use it as an iPod and you can't call or text on it. The way he checks this is by calling his phone off of our phone. So that's why I need to temporally turn it off for only a few minutes.
Please don't say:
"airplane mode"
"take out the sim" (I have an iPhone 4, the non GSM one, so it doesn't have a sim slot)
"put it in your bra" (the teacher literally said "We go through metal detectors, so girls, if you're thinking about putting it in your bra, or boys, if you're thinking about putting it in your pants, you're out of luck."
Please Help ME
thank you.

Added (1). I forgot to mention about the airplane mode, he'll be able to see the plane where the carrier is supposed to be haha
