grit
an ugly force for good
What can you do to make the user experience better? I've had on at least six phones now and even when I got free/inc video calls, didn't bother with them much.
Whilst Apple have made using things like the net on your mobile much easier, it didn't come much simpler then on the first nokia I owned that did years ago.
3G video calling has never taken off, there is no reason that would change with iPhones, its a user problem. A lot of the time people just dont want the other person seeing them, myself included.
