Tired of trying to search for this. Where's the best place to get a replacement battery for the 4S? I can replace it myself but I want to know who sells them that can be trusted. I will also need the tools and replacement screws. Also my speaker isn't working anymore. I'm hoping that it's just a loose connection. I'm thinking that's what it is because if I hit the iphone with my hand it will work for a little bit.
