I downloaded and installed a software update on itunes for one of my iphones. How to I get the update on my other iphone? I have plugged my iphone in and can see the download in my downloads but I dont know how to put it on my phone? Everytime I click update it tries to download the update again.
  
  Please help.
  
  Thanks
