500 - Unleashable or not ?

[henri_gomez]

I have a pair of R500 and wondering if I could upgrade them to unleashed.
When I read Unleashed FAQ, it's unclear 


Q: Is it possible to convert regular R500/600 to Unleashed and vice versa?
A: It is possible to re-flash an existing R500/R600 AP but please note that once re-flashed, an end user will have to repurchase unleashed support. We recommend purchasing unleashed R500 and R600 rather than re-flashing. We will be creating documentation that details this process to be available at launch.

But later on :

Q: Should customer purchase Support contract for Unleashed?
A: Support contracts are recommended for customers to purchase, so they can obtain the following benefits:  1. 24*7 Technical Support 2. Software Support, including Software Updates and Upgrades Although Support Entitlement is not enforced “on the box” at the time of product introduction the policies remain the same. That is, customers without support contracts are not entitled to the support deliverables listed above. However, we will continue to honor the Limited Life Time Warranty for Unleashed APs.

So can I flash unleashed firmware to R500 or should I get a special support ?
