To be used with voicestream the phone needs to be A GSM Band Phone, If it is it can be unlocked and used with the service, the old service provider has to unlock it. Analog, no even if its built in(doubt it) or has the nokia analog module accesory, the analog roaming feature is not available with VS any more as of JUNE 1st
First of all nobody has this phone yet and second of all I doubt VoiceStream will program it for you even if its an unlocked phone. VoiceStream sells only GSM phone's and does not support analog or TDMA roaming.
When did Voicestream stopped supporting analog? They used to offer the Nokia 6190 which is GSM and supports analog. Also, who was the analog carrier Voicestream used? Just curious...
