IPhone 4GS charger not working?

I just got a new IPhone 4GS 2 weeks ago and charger suddenly stops working. I don't know why and now my phone is dead. I tried a different cube thing and I tried charging through my computer but it won't work. The head of the charger where it goes in the phone seems to be fine so why isn't it charging???

Broken iphone 3gs, help!

Ok, basically, despite me shattering the screen and dropping it the down the toilet, it's worked fine for music and apps. But it recently ran out of battery, and now it'll only turn on if i plug it into the wall.As soon as i unplug it, it turns off and i've tried the reset, but it still refuses to turn on. (also tried plugging it into laptop). Its really annoying because when its plugged in, the apple logo will come up, eventually it'll say connect to itunes but it will immediately turn off if i unplug it. Rather annoying! Im pretty sure this has happened before, but i cant remember how i sorted it, and i have never replaced the battery. Luckily Im getting a new phone in a couple of days anyway, but it'd be nice to be able to listen to music for the next few days! Any help at all ?
