[OSX-Users] iPhone 4 facetime

[David Tarrant]

Ok so facetime only works over wifi.... so does that mean that your operator (O2) will still charge you for the call?

Reason I ask is if the voice and video are taking different routes then there is some skill involved in syncing the 2 at each end!

I guess they keep the cellular call in mute just in case you need it without video, or the wifi drops out.

If they do sync the wifi to the cellular call, that's clever.
