Iphone is complete dead

Hi there,

I am posting this, hopping that someone can help me because I have tried everything with my iphone an I am so far, no good news.

I have a 2G iphone 8GB and suddenly, the screen gets dark and without any response. Simple doesnt turn on and itunes doesnt recognize it.

I try to charge it (all night long) and doesnt get hot anymore (in the first time I charge it after I notice the failure, I connected it to PC and was hot but no itunes connection).

I tried all kind of buttons combinations (power + home; usb cable + home and others that I saw in the web) and nothing.. DEAD!!!.. and as you all understand.. I am getting like him .. DEAD for is beeing DEAD!!!

Can someone help me please?!

PS: My USB cable have 5 copper connectors. Is that the correct cable? I am asking this coz my brother have a iPod touch and I dont know if we change the cables and coz iPod cable doesnt work on iPhone.

Many thanks guys. Cheers. Hugo
