I received an email from AdMob on Aug 3 stating they had begun processing a payment "for all unpaid earnings accumulated through the end of June 2009". At least a week later I received a cheque in the mail. This has been the norm since I started collecting earnings. If you use PayPal, they are supposed to get you your money quicker. (I have refused to set up PayPal or even enter my tax information because their page for that is not secure, using only
