12 Steps To Replace iPhone 4 Earpiece Speaker -Replace a blown-out earpiece speaker in your iPhone 4

And then use a SIM card eject tool to eject the SIM card and its holder.

Remove the SIM card and its holder from the iPhone

Your iPhone 4 rear cover may have either two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws. Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.
