The software update menu item is missing.
When I click Settings...
The top section just says About and Usage.
There is no menu selection for Software Update.
What Operating System is on the phone?
Thanks for your posting.
The version is 4.0.1.
I guess this answers the question. Before 5.0 the upgrade requires iTunes.
Correct, the Over the Air upgrade functionality is available only after upgrading to iOS 5
thanks for this discussion... it helped me with my question as well.
