Sprint today announced Samsung Epic 4G and Galaxy Tab will get Sprint ID beginning March 21. Device users will be able to download “ID pack” – including apps, widgets, ringtones, wallpapers, shortcuts and more – tailored to their specific interests, business needs or favorite brands in a single download.

“We are very pleased with the success of Sprint ID and excited to expand this rich mobile experience to customers with these two popular devices – Samsung Epic 4G and Samsung Galaxy Tab,” said John Carney, senior vice president consumer marketing at Sprint.

All existing Samsung Epic 4G and Samsung Galaxy Tab owners will be prompted this week to accept the over-the-air software update for Sprint ID and Froyo in their device’s notification tab.

The software update for Samsung Epic 4G will also include the Android 2.2 (Froyo) operating system update. This update will add numerous capabilities, including Adobe Flash Player 10.1, Bluetooth dialing and allows app installation to external storage.
