I know there are lots of comments that some folks have issues. Maybe OTA will fix it etc etc. My wife called my from Beijing, China on her Incredible to my Incredible here in California. Sounded PERFECT. Crystal clear no issues on either end. FWIW data has worked perfectly. She can access some sites like Facebook that the wifi in her hotel firewalls. The network itself was pretty amazing too. No call lag whatsoever. That's all.
