our phones do indeed support rev. A the spec sheet for the msm 6500 (our chipset) indicates this:
"Supports CDMA2000 1X Rel. 0 and Rev. A, CDMA2000 1xEV-DO Rel. 0 and GSM/GPRS networks"

Also it occurred to me that if indeed this is true it'll only apply to Power Vision subscribers who have been using it since they got the phone, otherwise how would it be more cost effective?
