Hi, i’m reparing my iPhone 4. But i have one Question does the iPhone 4s Speaker fit in the iPhone 4? I ask cause the speaker of the iPhone 4s is a lot louder

May be it fit in iPhone 4 . the antenna cable in 4S is bigger than in iPhone 4. Speaker module is almost same . if you are thinking to change the speaker than iPhone 4 will give a more sound than old iPhone 4. its not working i think . i changed the 2 iphone 4 with Speaker module due to low sound in one iPhone . it never work . you can try .

I just swapped the speaker from my iPhone 4s into my CDMA iPhone 4. I needed to swap the antenna, which required soldering. Otherwise, it seems to work fine. I don’t know about GSM iPhone 4’s though
