Most carriers could really use some capital right now, because many still have to build out their networks.

WorldCom and AT&T basically have a duopoly on Fortune 500 customers.

They have established a very good brand, but is it worth any money?

It's really a question of whether there's going to be a global unifying standard. You're going to have three different wireless technologies, from three of the biggest [carriers] in the U.S. I think that's something to consider in terms of the applications that will be available, and people being able to use them.

The fact that they can double their voice capacity is a claim you're not hearing much from other carriers.

This is a major disappointment.
