Forgot iPhone UserID & Password. IPhone is locked

My friend restored his iPhone, when it turned on it asks for ID and password. He forgot both the ID and Password. (no point of resetting the credentials)

He has the bill of purchase and the box, so would Apple Center unlock his device?

(I read on internet that they won't unlock the device even if we have bill of purchase as a proof, Is this true? )

Would an elephant make a good pet? I think that they might, Maybe you can tie it to a tree in the backyard

I have heard that some animals make great pets. There are rabbits and parrots that are pretty cool. There are also more unusual animals like a donkey and a deer that are supposedly also good as a pet. Now, I know that an elephant can get to be a little large, but I understand that they are smart, kind, and can understand English. Heck, I even saw on the TV that some can paint, like music and can work an iPhone. Would they make a great pet?

How long does it take to get used the iPhone 7 plus?

I just traded my iPhone 6 for the larger iPhone 7 plus 2 days ago. So far I love it with its awesome screen and battery life. My only problem is my hands I have to stretch them if I'm using 1 hand while searching on the web. I'm a right handed person so it's hard to click the back botton with 1 hand. I heard they allow a botton to shrink the top half down to allow for easier access which helps to reach the top apps but using the web is hard using 1 hand which I'm used to doing with the iPhone 6. I have no problem using the phone with 2 hands but sometimes it's helps being able to use the phone with 1 hand.

Would it be legally normal for Law Enforcement members to give a civilian spy monitoring equipment to help them spy on their neighbor?

If police, FBI, or CIA were investigating the neighbor would it make it legal for them to use the technology to help spy on them? My example would be monitoring the targets home phone service so they can receive the incoming phone calls of the target home phone so that they can receive the phone numbers of the people who are calling the target house so they can spy on the people that call using their number as well. When the target phone makes a phone call, they can listen on whom they are having a conversation with real time and know what number they dial so that they can spy on the phone number they dial as well. If they use a mobile device such as an IPhone, or Android Phone, if they just have the number of the phone, they can track them, receive their outgoing and incoming phone calls, receive their texts messages outgoing or incoming. These software programs like Highster Mobile, Auto Forward Spy, ddi utilities that use to claim that you needed physical access to the phone you wanted to spy now say that you do not need the physical access of the phone you just need the login information. However, from many people that I have talk to they say all you need is the active working phone number of the target phone. Anyhow, is it legal? If I can prove my neighbors are doing this what can I do legally have them arrested.
