So how do you install it? The process is pretty simple:

1.
Download the update from Google’s servers.
2.
If you aren’t rooted or aren’t using ClockworkMod recovery, rename the file to "update.zip."
3.
Plug your Epic 4G into your computer, mount it as a USB drive, and copy the file to the root of its SD card (the main folder).
4.
Unplug the phone.
5.
Turn it off and boot into recovery mode (hold down the "volume down," "power," and "camera" buttons all at once).
6.
If you’re using the Epic 4G’s stock recovery mode, keep hitting the "volume down" key until you get to "Apply update.zip." Then press the "camera" button and confirm that you do indeed want to proceed. Alternatively, it you’re using ClockworkMod recovery, press the "volume down" key until you get to "Apply zip from SD card." Select it using the "camera" key, and then confirm your choice.
7.
Wait for it to finish flashing before selecting "Reboot system now."
8.
You’re done! Note that the device may take a little longer than usual to boot up – this is normal.
