According to an email forwarded to Phandroid, the promised 4G LTE upgrade for the Motorola XOOM is already available to tablet owners. The timing seems to be about right since the Galaxy Tab 10.1 will be available for pre-sale at a New York City Best Buy store tomorrow (June 8). Previous reports suggested that the upgrade wouldn't take place until the Tab was released.
