Ok so I want to transfer an app from my IPod to my IPhone. The only problem is that that app got deleted off the App Store so I cant just download it directly to my phone. Is there any way to transfer over the app onto my computer and then transfer it onto my IPhone? Also I am not on a Mac, I am using a Dell Intel PC so the ITunes looks differently then it would on a Mac.
Yes it is certainly possible. You need to sync your iPod via iTunes on your PC. All purchased apps should then appear in iTunes. You can then transfer them from iTunes to your iPhone.
Additionally, I recommend syncing with a computer regularly to ensure you have a backup of all your data. You are backing up right?
Here is Apple's support documentation on syncing: http://support.apple.com/kb/ht1386
