well given that the pone was thrown and mutilated by the impact, there can be many things that may have been affected. quite simply a wire could have broken, any component could have become faulty. you can use the tried and true method of using a known good antenna from a different phone to see whether it is the antenna or the logic board. hopefully it is only the antenna is faulty and all that needs to be replaced. I hope that this is helpful and you get her device working soon.
