iphone 3gs problem

[kamen]

i have had my iphone for a bout a year now and my phone went dead so i charged it up and left it, came back and it my screen was all black?
i have tryed all sollutions that i can see on this website and none of them are working?
its not powering up? not on pc or from wall plug
i dont even see the charging image wen its plugged in just a black screen?
my pc wont even pick it up wen i plug it in?
i have even brought a new ipod charger and that still does not work?
i think maby the charger port is broken?
any help is much appriciated

thanks

Try cleaning out the charging port with the bottled air computer cleaner. If that doesn't work just take it back to apple and they'll fix it or replace it.
