Iphone 4 with cracked LCD backlight goes on and off all the time?

I bought an iPhone 4 with cracked screen to fix it. After I went back home with the phone I started to notice that the backlight goes on and off by itself all the time. The phone didn't and doesn't have service so far. The screen is completely cracked and some pieces are falling apart from the screen. Also sometimes it display the same alert as when you try to shut it off although the battery is fully charged.

IPhone 4 not working; can't hear music anymore?

I accidentally splashed it with a bit of water earlier and now I can't hear any music. I can still call and still hear the phone ringing but other notification sounds seem to be on mute. I can't even listen to the videos I'm watching on YouTube. My phone's in a bag of rice atm. Don't ask if you don't know why but ugh I wish it would just work!

Why can't I sync music to my iPhone with my new iMac?

I recently purchased my iMac and I'm trying to get it to sync with my iPhone 4S, which I've had for the better part of a year now. I've authorized the computer to the iPhone so that I've now used 2 of the 5 computers I'm allowed. The iTunes software is updated with the most recent version as well.

iTunes recognizes my iPhone as it comes up in the sidebar, and I can view my info, what music is on it, apps, etc… The problem is that I've downloaded music onto this computer via iTunes Store, with my apple iD and I can't seem to click and drag the songs I want onto the iPhone. Usually I click the song I want on my iPhone, I drag it to the sidebar where my iPhone name highlights and it drops in. This time, nothing happens.

Synching iPhone with new computer. Will I lose anything?

I recently lost my computer whilst on holiday and have recently purchased a new one. I'm looking to connect my iPhone 4 to my new computer but I'm worried that I will lose everything which is on the phone already. When I purchase an app, for example, on my iPhone, does that need to be backed up on my computer or is the purchase saved in my account so I won't have to purchase it again? There's a section for sync purchases so do I have to do this to keep everything safe?

I think I have also reached the permitted amount of computers you're allowed to sync your iPhone with and therefore have I deauthorise one. Does anyone know if this has any affect in my content?
