You can walk into an Apple store and walk out with a replacement.

If you had backups running to your Mac or PC (which can happen over WiFi automatically when both the phone and mac are on line power), you've got a whole-device backup that will have you up and running as fast as it takes the backup to restore.

If you backup to iCloud, you can even walk out with the phone showing a progress bar while it is restoring to the exact state you left the older.
