Once you run provisioning its done. no need to go back and open it. it should auto provision for you anyways so there shouldn't be any need to run manual provisioning. As for it being defaulted to telus, thats normal thats just the selection it does not mean that's what its provisioned for. As for MMS you have to install Archsoft mms for sprint. flyers and imnuts both have cabs located in attachments in my thread.
