I am farily new to the HERO and am trying to use the market for the first time to download EasyTether. When I hit the market icon and try to sign into my Google acount I keep getting the message below. And we do have the unlimited data plan for both our phones so does this message mean I am going to have to call Sprint CC or is it something I am doing wrong with the phone? Thanks for any help. "Can't establish a reliable data connection to the server" "This could be a temporary problem or your phone may not be provisioned for data services. If it continues, call Customer Care."
