Hi everyone. I have bought new iphone 4 factory unlock here in UAE and ask the vendor to put applications to the unit. He put up 250 application (Games, Utilities, Entertainment, etc.) and now i want to put up new application from my computer but i cannot put up 1 application only without syncing the whole unit and without removing the previous application from the store where i bought my iphone. My question is, How can copy the first application that is installed to my unit to my Computer? or How can I add up 1 application only using itunes without erasing the application that was from the vendors computer?
