Hi community< i am in need of some assistance, i would like to remove one of my computers that are stored in my iphone 4 under the itunes wifi sync, whenever i sync, it would sync to both laptops and i no longer want one of those laptops to recieve the sync stuff as i gave the laptop to my mom and i dont want to burn her eyes( joking of course)... seriously tho!! i found out how to deactivate my itunes account from that computer but i still need to delete it from the iphone, i just want the one there that i will be using to sync with...

So does anyone know how to do what i am requesting? If so i highly appreciate all the helps in advance!!
