Does itunes backup your songs?

So let say if i do a system recovery, when you download itunes again does it sync everything in your iphone/ipod once you plug it in your computer? Or do you have to save all the things you have onto a usb?

How to get by with a water-damaged iphone?

I accidentally dropped my iPhone in water for 4 seconds and took it out quick. I let it sit to dry for 48 hours and it turns on with the Apple logo and then it shows a wrong date (12/31/2012) a few times before going to the right one. It shows the menu and all but I realized the Wi-Fi signal is acting up (it switches on and off so I had to manually turn it off). The biggest problem was the signal with the 5 bars. It mostly showed "Searching… " for a few minutes before shutting off by itself. Please note that after 48 hours the only way to turn it on was charging through my external battery case. I tried charging it through my macbook but it only shows the Apple logo. My dad told me to do research and find options to fix it but I'm afraid that nothing else will happen and that I have no other choice but to buy a new phone. What should I do?

Added (1). Please note that my contract ended and that i had this iphone for 3 years. But it sounds like my dad really wants me to fix it but i literally just want to tell him that i need a new phone.

Any realtime application translator?

Back after a long time! How you doin' my kind helpers?

Ok, I installed a chinese app on my win 7 but it has no other languages except chinese!
I can guess what some of you guys may say so let me mention a few things:

1. The app has no language selection option in the installing menu, so you have no choice but installing it in chinese.

2. Even in the app itself there's no option for changin languate I checked all the options blindly and there was no other language.
So what I need is an auto app translator which translates all the words soon as I open the app. And about the app, Um… Consider it as some sort of PC Suite.somethin' like iTunes or 25pp appstore. Can you guys tell me which application can translate all that chinese words to english and in realtime as I open the chinese app?
Is there any translation software like this? I have senn the iPhone version of it.

I'll be glad, and vote all your answers…

Trying to sync my iphone to a new computer?

I took all my music files from my old computer on a flash drive to put onto my new one so I wouldn't have to lose all my music and when I downloaded iTunes I added it all to the empty library.

When I went to sync my phone it said I didn't have enough space to sync. I'm confused because it said it would remove all the music on my phone and sync the new but it doesn't have enough space, what am I doing wrong?

I found someone's iphone 4, how to find the owner?

Believe it or not i found an iphone 4 in the bottom of a river in new hampshire. It was in a lifeproof and works fine… Except i can't get into it because it has a lock. I want to get into it so i can find the owner and return it.
Is there a way to somehow bypass the passcode or possibly use "find my iphone" app in reverse to find the owner? (far fetched)

i've tried to hold down home and call someone from it but service is out
-there is no sim card so that hack won't work
-im not trying the emergency call hack either
-I tried to put it into safe mode but i could get that to work either. Any suggestions?

Added (1). I also don't want to restore it and when i say no sim card i mean there's no place for one because its an original iphone 4 i believe. There's no slot.

Can i replace my iphone at a tmobile store?

So my iphone 5 16gb's earpiece is almost muted for no apparent reason. You can barely hear the other end of the phone and only works fine if i put it on speaker. I was wondering if i can go to a tmobile store to fix it or do i have to do to an apple store.

Does using FB/Twitter on Wi-Fi use data (iphone5)?

So I recently got an iPhone 5 and have the 2g data plan, and I was wondering if I use Wi-Fi while using Safari, Facebook, and Twitter will it use my data?
Also - if I play games (I only really play Temple Run) so if I play temple run while I'm using Wi-Fi does that count towards data or will it use Wi-Fi?
ALSO: Near the top of the screen, my phone says Verizon, my cell bars, and then it differs between the curved lines and 3g. The curved lines indicate that I'm using Wi-Fi, correct?
I don't pay my phone bill, my uncle does, so I really want to be conscious about my data usage. Thank you (and sorry, I'm quite new to smart phones!)!
