Flappy bird available on my iPhone?

I've heard many things about how people with the game Flappy Bird still available on their phone can sell it, with the game still installed, for a lot of money. Is this true? I still have flappy bird working on my iphone 5c and if that's true, I could really use the extra money… But wouldn't that also be copyright illegal?

My first tattoo was too painful, how do I get through the next?

I recently got my very first tattoo. An 8x5 inch watercolor piece on the side of my waist from my ribcage to my hipbone. I thought I could handle it, no problem. I have about 15 piercings including a VCH so I thought I would do great… WRONG. I couldn't handle it. It felt like I just could not relax my body and zone out. I had eaten prior to it. I brought my iphone for music. I tried focusing on my breathing. After about 45 minutes, he completed the outline and I tapped out on the color and shading. I plan to go back and get the color after the outline has healed. I felt so incredibly bad for my artist too. I was jumping and clenching my stomach at the slightest touch. I could tell it was really frustrating for him… I don't know what to do for my next appointment. I'm absolutely terrified that I'm not going to be able to handle it the second time. I feel like even though I know the pain level now to better prepare myself mentally, I still might jump and be too sensitive. And of course, I don't want to make it harder for my artist. I don't want him to get frustrated and I don't want to move around and screw up his work. I expected pain, but everyone had told me that after a while, your endorphins kick in and you start to go numb. I just feel like this never happened for me and it only got more excruciating the longer I was in the chair. From beginning to end, it felt like the pain only multiplied. Even when he simply touched me with his finger, I would jump in fear of pain.

I'm not using numbing creams or getting drunk. But seriously, should I take a hard core painkiller or muscle relaxer? I've never had this issue with any of my piercings, but that's 2 minutes of pain vs. An hour. I thought about getting a deep tissue massage or something to help me relax prior to my next appointment, but I'm afraid that'll make me too sensitive. Does anyone have ANY insightful suggestions? Anything is appreciated.

My cousin's way too spoiled?

I'm like a older sister to my 10 year old cousin, she tells me everything.
But she has a little problem that she feels too spoiled, she has an Iphone 4 (getting a 5c) a Mac, she broke, she's getting another one. (a windows 8 or mac) she might be getting an iphone 5s or going to one direction, she chooses. She has a wii, a ninetendo, blackberry, ipad, plasma tv, and some more.
No, this isn't a joke.

How much does an iPhone 4 or 4S costs in Miami (unlocked)?

Well I want an iPhone 4 but where I live it costs a lot so I'm thinking on buying it in Miami where a brother lives and send it here to Peru but I was wondering how much does it cost, unlocked of course, so I can get a mobile plan from a company over here. Since I'm low on budget, a used iPhone 4 will do but everything must be working fine.
