My iPhone 5 want connect to iTunes? - 1

Added (1). When I plug my iPhone up to the wall it charges. The apple screen blinks on and off the whole time the phone never comes on. When I hold the home and sleep button it showes that the iPhone needs to be connected to iTunes, but when I connect the usb cord to the laptop it doesn't even pop up on the computer. I've tried this with an old charger and a new one and it still does the same thing. Could it be my usb port on my laptop? I'm using windows 8.

Text messages lost after iphone restore?

I recently dropped my phone, breaking the screen. While the screen was broken, the phone itself was still functional even though the display showed nothing. I could feel text alerts coming in as I took it to get repaired, unfortunately the only backup I had was from before those texts were sent so i no longer have them on my phone. Is there a way I can view the texts that were sent to me while my display was broken?
