Yes you can you can use the inbuilt FaceTime program or you can download such apps like Skype.
While the new iPhone is good for video conferencing, you still will need to be in a good location with minimal interference. I wouldn't totally rely on that if you have a very important meeting just in case.

The exact release date is 17th June 2009. To find out more go to apple.com/iPhone and you'll see info about iPhone OS 3.0 and the new iPhone 3G S. Which is the new iPhone with voice recognition and video recording.
with the new 3.0 software update it is expected to be possible
As you probably already know the new iPhone OS just came out. The reason why it is so popular is because it is the first phone to be capable of making a video call any where you want if you have wifi. Also Apple is a very popular company
Video chat, 720Hp HD video, front facing camera, retina dislpay,LED Flash, A4 chip
Yes, many of them. The next generation will have items such as video conference and solar charging!!
most of the improvements (speed, new apps, fixing bugs, etc.) are just software changes, so your old iphone 3g is basically the same as the 3gs with the free software upgrade, the only real difference being that the new iphone 3gs has a built in video cam function. so, final answer, it is worth it if you do not have an iphone already (although the at&t service is a bit pricey) if you have an iphone already, just get the upgrade. (and if you really need a pocket cam/video recorder, just buy a flip cam for like $99) IMPROVEMENT: if you want to record video on your original iPhone or iPhone 3G, there's an app for that! (GET IT IN CYDIA)
