My iphone says it HAS to be restored?

So, I plugged in my iphone 4s to the laptop just to upload/update apps/music. Apparently there was a new software update and after downloading it it's saying I have to restore my iphone in order to use it. The screen on my phone is showing the iTunes symbol and the plug end with an arrow (I guess stating I need to plug it into iTunes)… It brings up "Iphone Recovery Mode" but says it's up to date. Why is the phone not working properly? Do I have to restore it and loose everything (apps, music, text, contacts) from my phone? Help! Thanks

Added (1). UPDATE:

When I plug in my phone to iTunes this message comes up:
"iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes"

Iphone4 is dead and it won't charge

My iPhone hasn't been charging for a while. It is now completely dead, there's a sign that comes its the thing that has the plug and then the lightning bolt, it keeps blinking on and off. It won't charge and its dead, I tried restarting it and turning of the power but nothing is working. When I charge it into other laptops/Pc/Desktops it still is not charging. I have no idea what to do now, help?
