MoneyControl's Market is a Blackeberry application that provides you with real-time updates not only on gold, but also on all business, economic and financial markets. If you're in the U.S. In the US, you can even use the app to find the best deals on gold and silver among local gold and silver merchants. Gold prices change every second and, if metal is important to you, you know that you must stick with the changing prices or they will rip you off, especially now that the Navratri and Diwali festivals are coming up, where gold is given away.
