I just discovered the operating system update yesterday. I downloaded and installed it in less than 1/2 hour. So far everything is running smoothly. This appears to be a secret update-only available until May 30th, so you better hurry. I downloaded the update using WiFi. Its about 400mb.
Apparently this doesn't work if your device is rooted or has an already modded OS.
