Sony Ericsson G700 touchscreen problem?

[PetruAlexandru]

Yesterday I was playing football with my friends,and accidentally the phone falled down from my pocket.Everything was fine until I wanted to use the touchscreen!It simply doesn't respond!

What could I do?

If the phone has warranty then take it to the store where you bought it from,other wise get rid of it(sell it)
