I'm bored in China. What to do?

Around late April, my parents said I had to be in China for three weeks to visit my grandparents and have a vacation in Beijing(for one week). Sadly, my parents taught me English before my Chinese, so I can't really communicate with people where I'm unless they ask me a question. I was hoping for Facebook to be around when I come here but I found out recently from a friend that Facebook and Youtube is banned here. I have tried asking my dad for a paid VPN but he said no, for reasons unknown (note: I have tried proxies and other methods, but they do not work). My mobile consoles like my DS can't be recharged as the amount of voltage in China is different to the USA's. Outside of my grandparent's house, there's pollution everywhere. Compared to the US, most people spit on the ground and throw trash everywhere, making a walk outside not enjoyable. The only sort of entertainment I have is my iPhone(can't call or text internationally), my laptop(restricted internet), exercising, sleep, and some gum. Please help, I feel like I'm going crazy without some sort of communication with the English world.

Added (1). I have Skype but my only connections are to 2 friends. Since they live on the other side of the world, I'll always be awake when they're sleeping and vice versa.
And what sites do you recommend for me to talk to people besides Omegle and Chatroulette?

IPhone 5 stuck on apple logo, how do I fix it?

So I jailbroke my iPhone 5 (ios 6.1) with evasi0n a couple of months ago. I recently tried to update some packages on cydia, and upon respringing, I was faced with the apple logo. I tried hard-resetting by holding the sleep button and home button, and then I held down the + volume button, but it wouldn't enter safe mode. Is there any way to get the phone working again without restoring it?

And in case some people are wondering, yes, jailbreaking is legal on iPhones, and yes, this question follows the community guidelines for yahoo answers.

I hope someone can help me and thank you so much in advance!

Problem trying to update iOS 7 Beta?

I have an iPhone 5, and I download these 2 files:
iPhone5, 1_7.0_11A4372q_Restore.ipsw
iPhone5, 2_7.0_11A4372q_Restore.ipsw

Whenever I hold shift (on a PC) and click check for update, I select either file, and for both I get an error message saying: "The iPhone ___ could not be updated because the firmware file is not compatible

my iPhone is 6.1.4, it's restored, my iTunes is up to date.

What do I do!

Problems with iTunes/iPhone?

I recently had to buy a new computer because my other laptop screen got stepped on. I thought that I transferred all of my music to the new iTunes on my new computer. However, when I went to try and remove some music from my phone, my iTunes library was missing most of the thing I wanted to remove. It was also missing a lot of things I didn't want to remove. I can hook my old computer up to the tv to look at it, is there a way to get my iTunes from that computer to my new one to fix this issue? Or is there another solution?

My iphone got lost someone found it and they won't give it back?

Okay so yesterday i lost my phone because it fell out of my jacket without me knowing. I realized i had lost it a hour and a half later and i looked for it outside and didn't find it. I still didn't give up looking so i called it and yesterday it took me straight to voice mail because the battery had run out but today that i called it would ring and ring like it does when you don't answer and then it sends me to voice mail. All day i have been calling and the same thing happens until a couple of hours who ever has it turned off since it took me straight to voice mail. My dad Gpsd it and it lead us to a house that really close by. I was wondering if this is considered them stealing it since they clearly know we're looking for it and they won't answer. Should i get the cops involved?
