Apps problems when syncing

[exuptoy]

Hey all, I have downloaded a pile of different apps and placed them in the apps folder in my music/itunes folder and even though they now appear on itunes, when loading to the phone it states cannot complete installation because they cannot be verified or something similar to that anyway. What do I need to do?

You need to go to "Store" in iTunes and click "Authorize Computer". Make sure that you have the iPhone plugged in when you authorize. Then sync. Make sure that you are using the iTunes account that you purchased the apps on and that syncs to the iPhone. Everything used in iTunes is account specific.

Hope that helps.
