Great success story on bootstrapping your business, and a big congrats because it's very a difficult road and will surely challenge your nerves and sanity. :) If your app has only been for sale for ~1 month, I encourage you to be very conservative with your spending — the AppStore is extremely volatile. While the momentum is in your favor with the Top Charts, I suggest you keep your eyes focused on improving the iPhone app and pushing updates. The other mobile markets aren't mature enough yet to approach aggressively, and sales on the AppStore could fall as quickly as they came.
