Here are UNOFFICIAL instructions for manually downloading the 2.0.3 update for the Kindle 2. They are a modification of the same instructions Amazon wrote for the Kindle 1 upgrades. I have modified them for the Kindle 2 update. I have followed the steps myself and they worked with my Kindle 2. I am not responisble if you try it on your Kindle 2 and they break your Kindle 2. You can always wait for your Kindle 2 to update on its own or for Amazon to release official instructions.
If you have the custom screensavers software installed, you will need to uninstall it first installing Update_kindle2_restore_default_screen_savers.bin. Then after you install Update_kindle_2.0.3.bin, reinstall the custom screensavers software by installing Update_kindle2_user_screen_savers.bin.
As for what's new in 2.0.3, Amazon has again not released patch notes, so we don't know what changed.
Updating Kindle 2 Without Wireless Connectivity
----------
Note: This software update only applies to Kindle 2. Please do not attempt to manually install Kindle 2 software on a Kindle 1.
You can download the Kindle software update to your computer and transfer the file to Kindle via the USB connection. The update process will take approximately 10 minutes.
When the update is completed successfully, Kindle will automatically restart and delete the update source file from your Kindle memory to maximize your available storage space.
If you are unfamiliar with using Kindle's USB connection: Please see the Using Kindle with Your Computer Help page.
If you receive an error downloading the file: You must be logged into your Amazon.com account and have a Kindle registered to your account. If you encounter an error, make sure you are signed into the correct Amazon.com account before attempting the download again. Please refer to our Signing Out Help page for more information.
To manually install the Kindle software update:
----------
Visit Amazon.com and make sure you're logged into the Amazon.com account to which your Kindle is registered. The download will not be available if you are not logged in before attempting step 2.

Set your Kindle power switch to the "ON" position.
Connect Kindle to your computer using the included USB cable.
Use your computer's file browser to copy the file "Update_kindle_2.0.3.bin" from your computer to Kindle's root directory. Do not place the file into one of Kindle's folders.
Once the file transfer is complete you can safely disconnect Kindle from your computer.
Use your computer to unmount or eject your Kindle and disconnect the USB cable from Kindle and your computer.
Press the Home key, then press the Menu key, and then select "Settings" from the Home menu.
From Settings screen, press the Menu key, and then select "Update Your Kindle". Please note that this menu option will be grayed out if the most recent update has already been installed.

When the update is successfully installed, you'll see a large checkmark on the Kindle screen.
After your Kindle has installed the update, it will restart. Once it has done so you will see your Home screen with only "Archived Items" listed and 0 books. Don't panic; it will take a minute for the Kindle reload the list of all of your books.
Verifying Your Software Version
----------
The current version of your Kindle software is listed in your Kindle Settings screen. If you see version 2.0.3 (327610024) listed, you have the most recent software version.
