thank you!
Do not know if this is standard on all or not.
If you've bought an unbranded NA102 flex directly from Motorola, then to be honest the simplest thing to do is to flash and flex the unbranded Cingular NA103 flex onto your phone. You will have to get the TMobile settings back onto the phone for Internet and MMS, which should not be all that hard. (You can manually enter them or get TMobile to do an OTA push of the settings.)
These phones are almost infinitely configurable, but you might have to learn more about your phone than you really want to know.
