Alltel, the CDMA carrier here in the U.S., just signed an agreement with Sprint Nextel to allow cross-network roaming -- for both voice and data services -- for a 10-year period. This includes EV-DO data, a data service that it does not have with existing roaming partner Verizon Wireless, where Alltel customers can only roam on voice and 1xRTT data (the older, slower standard).It's interesting that Alltel also has a wholesale roaming agreement with Cingular and T-Mobile USA, both of which are GSM carriers. It's still confusing to me on how a CDMA carrier has any kind of relationship with a GSM carrier, for whatever purpose. But, there it is.

1. Probably because when the roaming contracts were put into place, there was only analog. At least this explains the Cingular...the T-Mobile, I don't know because they have always been GSM only.
