Why has my iphone stopped charging?

My iphone is suddenly not charging. I've tried it in the plughole, and in my laptop, and using a different charger, but it wasn't charging, then a little while ago it started to charge, i nudged my phone away a little bit, and now it won't charge again!

Added (1). Its only about 4 months old

You don't say how old your phone is. The first thing I'd do is take it to Radio Shack & check the battery.

Sound's like a faulty connection in the charger's adaptor plug.
