I have no space on my iPhone 4s?

So I've had my iPhone 4s for about a year now and I have 1.5GB left. My phone only has 13.2GB on it. I went to my settings and went to usage and added up all the MB and it only comes up to about 2GB of space that I'm using. I've heard the new update i.O.S.7 takes up 3 GB of space (don't know if that's true) but even then that would only be 5GB being used. Does anyone have any explanation as to why i have no space on my phone?

Should I buy a PS Vita which is $249 to play Harvest Moon?

Growing up I used to play Harvest Moon: Back to Nature on the PS1 and recently just got this game working on my iPhone 5c using an emulator, but the buttons on screen make it kind of hard to play.

Do you think it's a waist of $249 buying a Vita just to play this game/other games too?

Video uploads to FB sideways?

Any way to restrict the Internet access on my iphone?

My phone is a huge distraction while studying and at school so I was wondering if there was a way I could restrict the Internet access to only let me do certain things (like send emails and text). I have tried using airplane mode but the that takes away all Internet and phone (I still need to receive calls from my parents in case of emergency). Also I can't just turn off my Wi-Fi/data altogether because I need my email and texting.

I have A LOT of homework every night, like average of 5 hours worth, and of course I have to take breaks but most of the time I end up browsing around my phone during the breaks and it ends up extending my total time doing homework to like 7 hours because once I'm on my phone, I can't get off. Texting is not the problem, it's random things like reading articles online and going on social media. Texting is actually helpful because I ask my friends questions and they ask me questions, which is why I don't want to turn off texting while studying.

So does anyone know of any way I can restrict my Internet access? I have an iPhone and I use safari browser. Are there any apps I should download or websites I should go to?

Can I use my iPhone on a cruise?

Hi, I'm going on a cruise tomorrow, and was wondering what to do about my iPhone 4s. I don't want to rack up any charges, so what should I do? Basically, just want to use my phone as a camera/video camera until I can buy a Wi-Fi package on the ship. When I buy a package, is there anyway I can call or text with an app or something. I'm going on a Royal Caribbean Eastern Caribbean Cruise on the Allure of the Seas by the way.
