This happened to me before. You have to delete all your apps of the iPhone and from iTunes. Then re-download all the apps from iTunes and re-sync your phone. You will not be charged again for re-purchasing. You'll get this message "you have already purchased this app would you like to download it again for free". Hope this helps.
iphone to mac transfer just two observations, as many above also note:the real news is the delay in the Playbook's release until summer. if the new batch of Android tabs goes on sale in the next couple of months with comparable specs/features, RIM will be too late to market, except for its enterprise base.
