It takes a lot of faith to shell out something like $600 for a 4G LTE tablet that isn't able to get on the 4G network. But that's what anyone who bought a non-WiFi Motorola Xoom did. And according to a tipster over at Phandroid, their patience has finally paid off. Because they received an e-mail instructing how to ship your Xoom to Motorola so it can get those new 4G goodies.

Thank you for submitting your Motorola Xoom for the 4G LTE upgrade. You should have recently received a package in the mail with instructions and materials for returning your device for the upgrade.

Our records indicate that we have not yet received your Motorola Xoom. If you are still interested in upgrading your Motorola Xoom, this is a friendly reminder to please follow the instructions provided in your upgrade package and ship your device back for the upgrade.

If you have already shipped your device back to us, please contact us at 1-800-734-5870 and one of our support specialists will assist you with tracking and completing your order.

Keep in mind, the tipster also said they didn't receive the packaging mentioned in the e-mail but that they had missed a FedEx delivery, which may very well have been the cargo in question. [Droid Life via Phandroid]

Update: Motorola recently contacted us with the following statement:

A very small number of Motorola XOOM users recently received an email from Motorola regarding the 4G LTE upgrade process. While we are very excited about being able to offer the upgrade this summer, and know our customers are equally excited about the benefits that 4G LTE speeds will bring to their Motorola XOOM, the email was sent in error. We apologize for any confusion this may have caused, and look forward to being able to share more specifics on how — and when — users can take advantage of 4G LTE on their Motorola XOOM in the near future.
