I had the same problem with the Hero when I tried to activate it originally. I had to have my sprint rep activate it for me because they had to change my data plan on my account so I could use android. I don't have the code for the new data plan. I would try the ESN swap online but i think you would need the premium data add on for the EVO to work. Wish i had an EVO to try it with.
