It looks like Motorola has finally announced when their Xoom tablet will get the 4G LTE upgrade, as they have started sending out emails to customers confirming that the upgrade will be available in September.

Motorola has been saying that the upgrade would be coming for the last few months, and many people were expecting it to happen before the end of the summer.

To get the upgrade you will have to ship your Xoom back to Motorola, and the upgrade will be available free of charge to Xoom owners.
