Got the 6.3a update and what a difference. Besides the Guide finally being somewhat responsive, recording a show is especially faster! In the past when I would set a Season Pass or just plain try recording a future show, it would sit with please wait for at least a minute or more. Now it's a LOT faster.
I'm sure it's been said but for those that don't have it yet, make sure your phone is plugged in and working. I just switched to Vonage and had to get that working first. I can look at my outgoing calls on my Vonage account and one morning when I saw it dialed out for a minute and then saw just a little later there was an 8 minute phone call, I was hoping that was the update. Sure enough, when I got home it was.
