If you all remember, there was to be a special version of VZW's Skype Mobile (called Skype Mobile with Video) that was supposed to launch with the Thunderbolt. Then is was supposed to be a month late. There was even a almost-finished version of it leaked. Then Microsoft bought Skype, which killed the project. So the standard Skype for Android app launched FFC support for Android 2.3 not long after that, to which the Thunderbolt received the 2.3 update in September? I think...
Long story short, there will likely never be a Skype Mobile with Video, but the standard Skype works fine, as well as GTalk and Tango. I use GTalk on a daily basis and have no issue with it.
