Your phone should still be under warranty, but I'm not sure if that is covered. If its not, well its prob. just cheaper to buy a new one. A screen is usually very costly to replace.

Talk to your service provider first.. As calling the manufactor will do no good as its uaually the service provider that does ALL repairs for cell phones... If the service provider is of no help, then try the manufactor as you might get lucky.

Best of luck
