If you are one of those people that think that the little icon bar at the bottom of the phone that pops up for app switching is just a real pain in the ass, then have I got the find for you. PhySwitch allows you to use the volume buttons on the side of your iPhone to scroll through live, full pages of the running apps. Simply touch it to enter the app. You have to have a jailbroken iPhone, but it looks awesome.
While I haven’t jailbroken my iPhone, I do kinda wish that this would actually become an app or at least a utility in the preferences. Although, Apple has a pretty tight, nay rock solid, grasp of what developers can and cannot do with the buttons on the phone. So, if you have a jailbroken iPhone, try it out and leave a comment.
