UPDATE You should return your EVO to the store it was purchased it at if your phone has been bricked, not necessarily a corporate repair center. Since all purchases are within 30 days at this point corporate stores are NOT able to handle exchanges from third parties such as Best Buy and Radio Shack. Furthermore, for those who purchased the phone through Sprint a trip to a repair center is not needed since any corporate store can process exchanges.
For those looking to purchase it the phone is back in stock online, but your results may vary at local stores as we've been told most retail outlets are still working through their wait list.
