How to delete an iPhone application that i got from iTunes store?

I downloaded an application from itunes app store, aftr i downloaded it i realize its completely useless and i want to remove it coz its a waste of storage capacity and memory of my phone. I cant delete it like other app that i got from installous. Pls help thanx|||If you get it from installous you should be able to unintall it by holding your finger on the app for 3 seconds and then clicking on the x in the corner of the app. I think you may have gotten the app from cydia so you should go to cydia and the click on packages and you should see the one you downloaded it. then uninstall it|||Find the app and hold down on it and then all your apps will start shaking. An x will appear in the top left corner. Click on the x and it'll ask you if you want to delete it.|||Hold your finger down on the app untill it starts to wiggle the press the X on the top left corner.;
