I think is $200 for a replacement no?
Make sure is the phone and not the charger or cable you are using. If it cannot be awaken, then if you had iCloud & Photostream active you can get back most things. Go to
www.icloud.com and see what you have there on the cloud for contacts & calendar. Photostream with iPhoto on mac or using the free photo stream software for PC from Apple so you can see them on your pictures folder. If you never used a cloud backup or an iTunes backup then you are SOL.
