Yesterday I set up Google Voice account and installed the app on my HTC Inspire. I declined allowing Google to be my primary vmail, but despite this, I am now having trouble with my ATT vmail. When I dial 1 to access my vmail I get error code "invalid MMI code." Have been in chat room with ATT forever and they can't get my phone working properly. They gave me support number for a local store and for HTC support. Anyone know how to fix this issue? Thanks!
