What cameras do people on Tumblr use to take pictures?

Seriously… How do people on Tumblr and Instagram take such nice pictures. Like I don't get it. When you use the iphone to take pictures it comes out a lil blurry but people on tumblr take high quality pictures. What camera do tumblrers use?

Falling in love over omegle?

Ok so before you judge me read this:
I'm 14 and today was the first day I ever used omegle i went on this morning cause I was bored and I know there are tons of pervs and paedos but I started talking to this one guy, who is 18, yes i know too old but he is amazing, remember this is video chatting so i can see what he looks like, definitely 18. He told me I'm cute about 10, 000 times not hitting on me, in a nice way like adorable and he's just so funny and we just like clicked and he kept smiling and laughing at my responses and I had this cheeky grin on my face for the whole half hour conversation
anyway we both live in england and he's honestly everything I love in a guy, my heart started racing after the first 20mins of the conversation, then I asked for kik and fb he lost his iphone and doesn't have facebook BUT he has twitter but he wouldn't give me his username because apparently 'it isn't the same on and off omegle' and I literally felt so sad cause he's so amazing and I'll never be able to talk to him again, his name is Tom but there are so many tom's out there and I honestly think I love him because I've had this with only one guy before and this time it was even more amazing.
my question is: is there anyway to find him again and do you think i've actually fell for him cause I do <3

Cool/cute things to buy for my iphone?

Then there's things like external fish eye lenses. Iphone cases.those things where you plug it into your phone when its dying and its like an external battery. I don't know what's something cool to buy for my iphone 5?

If you jailbreak the iPhone 4S?

If it is an untethered jailbreak and the power button breaks as it normally does with my iPhones, will I be able to return it? I have insurance and often return the old phone and they give me a new one, but I was just wondering if the jailbreak would affect that
