i want to sync my iPhone and create a backup copy, but after full process i get the message only 5 computers can be used, delete itunes from one of the old ones and then synch to my PC is terminated..
problem is, these computers are long gone to pc heaven or delivered back to my company, so i'm not able to clean them out now.
so how can i delete the registered computers in icloud/itunes ?
