US Android Users Can Buy Android Apps with Carrier Billing
In addition to the usual Google Checkout payment, Android smartphone users in US can now pay the Android Market apps via AT&T and T-Mobile US carrier billing. Announced last week, the new changes is only applied to users in US. The charges will add into your monthly billing account and yet still support the new 15-minutes refund window.

As for users in other regions, there is no news on alternate payment method as of now. Paypal has been rumored to support Android Market so hopefully it will get through sooner.
