Bad Connection: Inside the iPhone Network Meltdown

I thought I would throw this out there because I am sure someone here knows this.

The article said Qualcomm is working with Apple to make a chip that would allow the iPhone to operate on both AT&T and Verizon networks. Does that mean the chip would also work with Sprint by virtue of it also using CDMA or is there more to it than that?

I think there might be more to it than that. I think Sprint uses 1.9 GHz and 800 MHz frequencies, whereas Verizon uses 1.9 GHz and 850 Mhz.

But they both use EV-DO (specifically CDMA2000 EV-DO Rev. A), which is a standard...

On the other hand, it looks like Verizon is fast moving towards LTE. See: http://www.engadget.com/2010/07/18/verizons-lte-rollout-is-i...

and

My guess is that the next iPhone supports LTE and is available on either AT&T or Verizon.

Sprint, on the other hand, is only now thinking about using LTE:

I doubt that a single iPhone design will work on AT&T and Verizon any time soon. AT&T would need GSM+UMTS+LTE while Verizon would need CDMA2000+LTE. An omni-protocol super-chipset is possible but unlikely.
