How to get black emojis on iPhone?

I'm talking about these "✧☪"
They show up black on Instagram and I have no idea how to get those. Or the little black heart. I use emoji, but it just comes up with the red heart. Any help?

Digital keyboard for foreign languages?

OK, so I'm not sure if they even make this, but ideally I'm searching for a full size keyboard version of what the iPhone, or other touchscreen phones can do; ie show locations of letters of a different alphabet. I realize that computers have regional settings and keyboard changes, but that doesn't change the actual printing on the keyboard. I'm a foreign language major, and I learn too many languages to deal with tons of keyboard stickers. Arabic. Thai and Russian are the most ideal examples. Anyone know if such a keyboard exists?

Added (1). I already mentioned I know how to change the keyboard setting on the computer. But once again, that's not what I'm looking for. I don't want to fumble around pressing every key until I find the right one. It would take me 30 seconds to type 1 word.

Is my iphone 4 locked or unlocked?

I have a iphone 4 that had att service, I never paid the bill and after 2 months the "at&t" sign in the top left of my phone screen switched to "no service". If I want to sell the phone does this mean it's locked or unlocked?

Is Microsoft Surface Worth The Price?

I'm saving my money for a tablet or a laptop, I decided I'm not going to get a laptop for the simple fact i only use my current one for music or social media. I have narrowed down my tablet choices to iPad or Microsoft Surface. The iPad is $399.99 and the Surface is $499.99 the surface is a 32gb comparing to the 16gb iPad. I only get paid $150 a week (underage kinda job) so i have to save 3 weeks for a iPad or 4 for the surface. Is it worth 4 weeks? I like the surface because it has a lot of office features, which i enjoy working on that kind of stuff. But the microsoft store doesn't have a lot of apps comparing to the iPad. Which is a great factor for it. But knowing i already have an iPhone and iPod i don't think i need games that much. Which should I get? Opinions on products? Worth the wait? Maybe a laptop is better?

How many dance classes can I get with this extra money?

Okay, lets say 1 dance class per week from sept-march/may costs $700. I don't really know how much a phone costs and a yearly plan costs, so how many dance classes can I get from lets say not getting an iphone my parents want to give me (which i really don't want, i want extra dance classes) AND the average amount of a yearly plan?

Which type of tablet should I get?

I'm going to save up my money. I can't decide what tho. Its between iPad, Acer Laptop, or a microsoft surface tablet. The surface is more for school stuff, and thats okay because i already have a iphone and ipod for apple apps. My current laptop has a bunch of problems, but i really only use it to listen to music now. I'm trying to narrow everything down. Please give your opinions on the items
