I'm a clumsy boy, and often drop my phone when I don't intend to. Recently I have been experiencing an issue where I have zero bars and no service whatsoever, not even emergency calls. Done all the shabang, checked sim card in other phones, new sim, factory reset etc, so I'm guessing it's a hardware issue. Is there any way this can be fixed, perferably cheaply, and is it possible for a well educated technician to do it and retain some level of water tight seal?
