Well, neither does my Galaxy Nexus, just sayin...
I would hope the Rezound wouldn't have issues, they've been able to perfect things with the Thunderbolt. You don't think the Rezound will have some bugs here and there when they update it to ICS? Good luck with that. I had the Thunderbolt and since it was their first LTE phone there were issues.
Guess what the Galaxy Nexus is? It's Google's first LTE phone and their first ICS phone. Now it's not Samsung's first LTE phone, however Samsung just got the Charge to become a decent phone after it's last update and guess when that happened? Right before the Galaxy Nexus was released.
