I'd first suggest you go to disk utility and run permissions: verify and repair, and while there take a moment more to run disk utility. I am assuming that the apps downloaded have been confirmed compatible with the IOS on your iphone and that you have downloaded apps before for the iPhone.

Have there been any recent updates installed on either device?
