iPod iTunes not displaying iOS device content

[spectralsea]

So I have an iPhone 4 and an iPad, both running iOS 4.2.1 under iTunes version 10.1.1. For some reason, whenever I click any of the content tabs under each device (Music, Books, Videos, etc.), iTunes shows that there is nothing on the device even though I can clearly play and view the content on the device itself. I know there have been some issues with 4.2.1 and content not showing up on the device, but has there been any sort of fix on content not being viewable through iTunes? Thanks!
