I can not sync some of the Apps and Games that I got with my phone to iTUne libraby. My phone is jailbroken and 3.0 firmware.

Everytime I try to sync the apps and games a window pops up and says following... I already authorize my computer but it still doesn't work.

Some of the purchased items on the iPHont "name iPhone" including "YPmobile", could not be transfered to your iTunes library because you are not authorized to play them on this computer.

To authorize this computer for items purchased fromt he iTunes Store chosse Store > Authorize Computer .
