Does boost mobile work in Ireland?

I'm thinking of ordering a phone off the boost mobile website. It is an iPhone SE but I'm not sure if it will work in Ireland. Also is there an easy way to unlock it to use meteor or Vodafone.

After restoring my Macbook computer, it says I no longer have an Apple ID?

I had to reformat my computer after having many problems with it, and now when I try to sign into my Apple ID, it says that my username doesn't exist. I'm taking this to mean that my account was somehow deleted. Because I also have an iPhone with the same Apple account, what should I do next? I don't think making another Apple ID will help me with my issue.

Glass is separated from LCD on iPhone 6?

I bent my iPhone 6 and the screen got separated from the frame. I started to try to take the screen off but the LCD is separated from the outer glass surface so that when I use a suction cup to pull it off I'm only pulling on the glass. (The LCD is still attached to the frame). Can I just keep pulling and hope it comes off or will this crack the screen? Anyone have any recommendations?

Thanks

Also, I don't know tech lingo so if I explained anything wrong, tell me so I can update the question.

Why are there buttons on the bottom of a cell phone where your palm would activate everything via heat if you pick it up from the front?

On my old iphone 6plus and my new galaxy. Everytime I wake up and grab the phone to shut down the alarm. Since I'm grabbing the phone pretty unconsciously. By the glass part.

I'm usually warm so my palm, if it goes near the buttons. The heat activates ALL the buttons at once.

Then the alarm stays on while every app on my phone starts to open just because I'm near those buttons.

Why can't the buttons be on the top near the ear part? This is just how I grab phones because the designs are so stupid and slippery.

Buttons at the bottom seems like some sadistic torture idea for people with normal sized body parts. If I was a child or someone from a culture who builds these my fingers would obviously only be an inch long so it wouldn't be an issue. But I'm 6'.

Iphone lost and found

My iPhone5s was stolen a month ago.
I could find the details of person using my iPhone using FindmyiPhone.
The thief had sold the phone to a shop.
The shopkeeper somehow managed to hack into my iCloudaccount, turn off find my iPhone, and reset my phone.
I could get hold of the shopguy via police complaint and infbon FindmyiPhone.
Now that I have got my iPhone back, it's logged with unverified iCloud account of the shopguy. I can't remove it or reset my device.
I don't have contact with shopguy anymore and have 0 chance of asking his iCloud password to signout.
