To install it you simply download the update.
Open iTunes and attach your iPhone. In iTunes, Option Click or on a pc shift click on “Check for Update.” A window will open and you can select the file you just downloaded. Apply it and it will start the update. Once completed it will ask if you would like to restore from the backup it has of your iPhone. Choose yes, it will do so, then restart your iPhone.
Once it is done you can sync the applications you downloaded from the iTunes Music Store. Don’t forget to set the applications to sync all. I turned off all of my music and podcast updates because I did not want to wait for them to restore. I will deal with that later.
I will write some blogs on some of the apps I have downloaded and installed later today.
