My main Google account is based on my enterprise gmail account, i.e. I have a domain that is pointed to the gmail servers but my email is not @gmail.com. I set this account up with Google Checkout, but the Android Marketplace on my DX won't recognize the account for purchases. I realize that the enterprise accounts have some limitations compared to a straight up gmail account, but if Checkout can be assigned to this type of account, then why won't the Marketplace/phone recognize it. I REALLY don't want to have to create some dummy gmail account just to buy apps! Any help would be appreciated!
