While it's not applicable in the next ten days, WiMax/802.16 will make these sorts of issues kinda moot. AT&T and Covad are kicking into high gear in the next 6-18 months to roll out their WiMax services. I had been researching the same sorts of things mentioned in this thread, including GSM/GPRS and CDMA services, but I think I am just going to wait until WiMax is out...my call needs are still limited to the continental US and my AT&T cell phone still works just fine all over the country. ;)
