iPhone "Update All" not working

[mknabster]

I seem to be having an issue with the App Store on my iPhone 5 lately, where the App Store says i have multiple updates available for my apps, when the "Update All" option at the top is greyed out and it cannot be selected. When i try to select Update now for each individual app, all it does is launch the app in question, but does not update it. I tried turning the phone on and off to no avail. The next thing i'm going to try is connecting to to my computer and let it update that way, but why wouldn't it work on the phone itself?
