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?
- jesseendahl 16y agoI 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.

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: http://gigaom.com/2010/07/13/sprint-going-lte-makes-sense-but-not-a-t-mobile-merger/ http://gigaom.com/2010/07/13/sprint-going-lte-makes-sense-bu...
- wmf 16y agoI 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.
