The Epic 4G, Sprint’s Samsung Galaxy S version, appears to be the first handset to get the Android 2.2 upgrade, which is definitely great news for Sprint subscribers that currently own an Epic 4G. The official Froyo build for the Epic 4G is now available to download and install on the smartphone, and in case a Sprint OTA update hasn’t hit you yet, then here’s what you need to do to install Android 2.2.1 on your Epic 4G manually:

2. If you aren’t rooted and you 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).
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.

Note:

• The method described below will not work if you’re already running a custom ROM. Therefore, you should use the method and the files at this link to update if you’re using anything other than the stock Éclair software that came with the Epic 4G.

The update includes all the Android 2.2 goodies, including Adobe Flash 10.1 compatibility, a JIT compiler that drastically increases performance, and that oh-so-handy “Update All” button in the Market (not to mention the new “Related” tab, which was also included here). However, Samsung has also upgraded TouchWiz from 2.1 to 3.0, which includes a few updated icons, a new “Silent” toggle in the notification bar, and the ability to add/remove homepages.

Are you planning on updating now using the instructions above or waiting for the official OTA to roll out? Let us know in the comments below. And, as usual, stay tuned for more news and info by following us on Twitter and/or by subscribing to our RSS Feed.
