Need iPod Touch to recognize copied app
Here's the deal. A little after I downloaded a bunch of applications, I reformatted my laptop and forgot to backup my apps first. Obviously, syncing my apps now would only erase what's on my iPod.
I found a program called iFun Box which very nicely allows me to add and remove files as I please. I will be selling my 3rd gen iPod Touch soon but would like to save all of my apps first. I tried testing this by deleting an app and then adding it back manually. There's just one problem. The app is where it's supposed to be but it's not showing up on my iPod screen. Is there any way I can get the iPod to recognize those files? I'll need to know how to do this when I get my iPod Touch 4th gen. Thanks in advance for any help.
P.S. My iPod is jailbroken.
