"A terse statement from AT&T Monday said "we periodically modify our promotion and distribution channels." An AT&T spokesman declined to comment on why the carrier temporarily stopped online sales of the iPhone."
It is anyone's guess as to what really happened, but I suspect the embarrassment of the incident prompted AT&T to quietly reverse course and release the non-explanation. I wouldn't doubt it if Verizon's marketing group was already working on the dialog and story board for another ad poking fun of the device from the Island of Misfit Toys.
It would be funny if the issue weren't so serious for iPhone and AT&T users. It seems AT&T is going to great lengths to mitigate the problem without actually beefing up the network. Of course, I know they are working on improving the network but it is slow going and the complaints continue to mount up.
