Cristian,
If you are asking me if the IOS upgrade is free or not, that I couldn't
answer. It all depends upon how you like to pay the piper. :-) If
you have smartnet maintenance, then I think it is free. If not you will
probably have to purchase it. I am no expert in this area, maybe someone
who works for a reseller can help you out here....
.....Bueller? Bueller? anyone? ;-)
Later,
AQ
