IPhone 4 app stuck installing

I was trying to update my snapchat app and It was stuck installing so I went to my settings and deleted the app but when I did it's still there but on my settings it says it's deleted. So I tried to sync my IPhone to my computer to delete it that way, also won't work. Tried restarting my IPhone. Won't work. Also tried disabling my restrictions and that won't work either! AND disconnecting my Wi-Fi and reconnecting back on to it! I'm out of Options! So Please Help ME!

My iphone is not turning on? - 1

My iphone 4 turned off all of sudden while I was using. The battery was fine. Then I plugged to the wall charger and the apple logo appeared but nothing else. Suddenly it showed that screen that asks to connect to itunes. I unplugged from the wall charged and plugged on the computer to connect to itunes and the phone died completely.

I've tried pressing home/power button in all sorts of ways that I've read about it and nothing works.

Please let me know what I should do. Is there any other possibility besides seeing a technician?

US Tmobile unlock code does not work for my iphone 5?

I followed the unlock code step but it does not work for my iphone5. Then I restored the device as the code said but it still not work. The error is "Your iphone could not be activated because the activation server is temporarily unavailable. "

2. Connect your iPhone to iTunes
Important: This step must be performed using the USB cable connected to your PC or Mac in order to trigger the process.
3. Within a few minutes, a screen will appear, "Congratulations, your iPhone has been unlocked".
4. The device is now unlocked. You may now insert any non T-Mobile SIM card into the iPhone.

Iphone plans for a low cost?

I'm looking to get an iphone but i really don't want to spend like $100 a month on it. I've looked around a bit and discovered straight talk and virgin mobile. The area I'm in (long island NY) has bad at&t service which was said to be bad for straight areas with good at&t have better service and internet and since the phone is $650 and i have to pay $45 a month, i thought i should just find something better. So how well does virgin mobile work for a 5s and in the long island area? From my mom and friends, i've concluded that verizon and sprint are probably the best carriers in my area. Also, are there other No contract plans that might work for me? I've heard of vonage but i don't know much about that
