More bars my ass...

From the nytimes article on the iphone

The bigger problem is the AT&T network. In a Consumer Reports study, AT&T’s signal ranked either last or second to last in 19 out of 20 major cities. My tests in five states bear this out. If Verizon’s slogan is, “Can you hear me now?” AT&T’s should be, “I’m losing you.”

Then there’s the Internet problem. When you’re in a Wi-Fi hot spot, going online is fast and satisfying.

But otherwise, you have to use AT&T’s ancient EDGE cellular network, which is excruciatingly slow. The New York Times’s home page takes 55 seconds to appear; Amazon.com, 100 seconds; Yahoo. two minutes. You almost ache for a dial-up modem.

Ha, I knew that Cingular and now AT&T's cell phone advertising was a load of BS!!!
The only plus of either company is they have more coverage in the rural areas of many states, ie OK where every other cell company (except the state specific baby ones) only have cell coverage in major towns and along the interstates.
