I can’t remember the last time I was so excited about a jailbreak app. Maybe it was for Action Menu, or for mQuickDo? I’m not sure, but what I know is that ProSwitcher has radically changed the way I use my iPhone.

ProSwitcher is a multitasking app for the iPhone that kinda replicates the Palm Pre “cards” feature by adding a very nice UI to Backrounder, the jailbreak app that allows you to run apps in the background.

I never was a fan of Backgrounder. Having to close the app to launch another one kinda defeated the purpose. But ProSwitcher makes app switching seamless, and I have to say, with a certain style.

9 to 5 Mac gives a pretty good description of how it works:

You can trigger the cards view by opening the application from home-screen, touching the status bar, or by double clicking the home button. To add an application to the Cards view, you simple have to launch the app, then hold down the home button for about one to two seconds. To remove an app from the “Cards” view click the close button on the top left of the card, to swipe the card up the screen.

I ran ProSwitcher on my 3GS for a few hours with up to 10 apps open at once. It didn’t crash, it didn’t lag and the battery didn’t seem to take a big hit from it. Obviously your mileage may vary…

What I like the best about ProSwitcher is how you can smoothly switch between apps without having to close/reopen them. Actually no! What I like the best about ProSwitcher is that it is free on Cydia via the BigBoss repo. Yes it’s free, so grab it until the dev realizes that he should make you pay 10 bucks for it.

ProSwitcher is one of this application that should be implemented in the next iPhone OS and honestly, I really believe (and predict) that Apple is already stripping down the code of this app and trying to make it its own for iPhone OS 4.0.

Have you tried ProSwitcher yet? How do you like it?
