Can i flash a verizon iphone 4s to another carrier like metro pcs?

I've been searching for hours with no real solid answer… So here is a little background.
My sister lives out of town. She came to visit and told me how she bought a verizon iphone 4s that is a A1387 model. She bought it off craigslist and of course you guest it, it had a bad esn. I told her the first thing you should check before buying ANY PHONE is that the esn is clean… Anyway she ended up buying paying full price for a virgin mobile iphone and so i told her i would give her some money and buy the one she bought off craigslist and just use it as a ipod. I now wouldn't mind seeing if i have any options in using the phone.
So… What i'm wondering is
1. There's any way outside of a factory unlock I can unlock this phone. I no i can't jail break it it is running ios 6.1.3, but is there any way that i can unlock it for use with another carrier such as straight talk or pageplus
2.Is the Gpp unlock sim legitimate ( optional base on knowledge and experience)
3. Since the phone is cdma and gsm accessible, can i "flash" the phone to another service such as metro pcs. This option is the one i'm hoping for the most

Also any information on my options to get it working would be great. All answers and response I have found were mostly from 2012 and before the laws or whatever passed to forbid unlocking and etc after a certain date

Why is my Apple TV Airplay so slow?

I have the Apple TV 3rd Generation and Airplay is So SLOW using all of my Apple devices. It's unbearably slow… To where I don't even use it (what shows on my computer won't show on the Apple TV until MINUTES later).

I have tried it on my 2013 Macbook Air, iPad 2 and iPhone 4 and it is So slow on all of them. I'm connected through Wi-Fi and have a really good router… I don't know what the problem could be. I don't normally have problems with my Wi-Fi connection so I'm very stumped and am bummed that I can't use the Airplay feature because that's the main reason I wanted the Apple TV!

I was wondering if any of you knew why it is so slow and how I could fix this?

How much data will i use on an iPhone?

I'm going to be getting an iPhone soon but i was wondering how much data i will need on my plan. Most of the time i will be on Wi-Fi like at my house and at work and probably school. However when i'm out and about i want to be able to use some data on my phone. I know its pretty hard to know how much data i will use but lets just say i use Facebook or instagram a few times and maybe Pandora or some sort of gps app during the time i'm using up the data, how much do you think i would generally use a month? Sorry this is pretty vague i'm just trying to get a better idea how much data i will need to get on my plan!
