Yep. The device makes the network.
Crazy statistics. Ironically it's the device that is killing the network. Millions of new data users wanting the iPhone meant whomever the carrier is would have to compensate with a huge demand of new power. While AT&T has certainly been raking in the dough they should also take responsibility for slowly adapting their network to such demand. However, dealing with zoning and building new towers makes it even more difficult. Hopefully another US carrier having rights to a network compatible iPhone will be a win/win for everyone (win for those wanting it on another network and win for AT&T customers that will have a less taxed network).
