Another generation of Motorola Linux Phones (don't know why people think OpenMoko or Google are first in this arena; Moto has been at it for at least a year or two). This time with Two SIM cards ... but only EDGE speed (well, one has EDGE, the other has GRPS and CDMA). Otherwise, I'd look at using it for T-Mobile for voice/messaging and AT&T for data.
