I've had my Sprint Hero for around 4 months now, it is not rooted, running stock 1.5. I was trying to check the marketplace for any updates to my apps and it brought me to the set up google account screen. I've tried signing in and It tells me that there was an error on sign in and my SIM card might not be provisioned for data. Obvoiusly as a Sprint customer I don't have a SIM card, is there anything I can do to get things working again?
