[[UIApplication sharedapplication] Openurl:[nsurl urlwithstring:appstring]];
Among the system's appstring are:

1.Map Http://maps.google.com/maps?q=Shanghai
2.Email Mailto://[email protected]
3.Tel tel://10086
4.MSG sms://10086
OpenURL can help you run Maps,sms,browser,phone and even other applications. This is a piece of code that I often need to use in iphone development, and it's just a single line.
