Sounds to me like the phone itself might be a goner.
However, to be sure, try bringing it in to a dealer and getting it checked out. They will probably be able to recover photos/contacts.. etc.
You def dont have to get a new number if you don't want to. You can easilly switch it over to a new phone.
Nvm, not a gonner.
If just the screen is broken then your shit is all saved.
Just bring it in to them, see what they can do.
