Rooted or Unlocked Motorola Xoom tablets eligible or ineligible for 4G LTE upgrade?

According to a Motorola spokesperson on the official Motorola support forums, the rooted / unlocked Motorola Xoom tablets are eligible for 4G LTE upgrade.

Quoted from the official Motorola support forums,

All Motorola XOOM tablets on the Verizon Wireless network are eligible to receive an upgrade to support 4G LTE. This includes those that have been unlocked; however, those units must be submitted for upgrade with the original factory software reinstalled and the device relocked in order to receive the upgrade.

For devices that are returned unlocked, Motorola will attempt to complete the upgrade, but may be unable to update the software. In these cases, the device will be returned to the consumer with just the 4G LTE modem installed.

More details on the process will be available closer to the upgrade availability.
