Hey guys, my iPhone got bricked yesterday after I tried to install PDAnet. I had to do a complete restore and update to 4.1. It's working right now. However, I want to get a great tool that I don't remember the name. It allows me to multitask better. When I double-click on the home button, the cross button shows up immediately so I can close the app and also, the apps that are not running in the background are dim. Do you guys know which tool I'm talking about and where I can get it? Thanks a bunch.
