You'll have to have an itunes account to register it.
I think you can register in the iTunes app. If you are not logged onto an iTunes Library, you will be prompted upon entry.
If you just recently got a new iPhone 4, connect it to iTunes and iTunes will identify it as a new phone. If you have previously synced your iPhone 3G with that computer before, then iTunes should give you the option to sync the new iPhone with a backup from your latest iPhone 3G sync. When you do that, your files from your 3G will be transferred to your iPhone 4. Hope that helps :)
I had this problem too. I had iTunes installed already, but when I tried to sync my iPhone, nothing came up on my iPhone screen. I quit iTunes, and unplugged my iPhone, then plugged it back in and opened iTunes again.
You go onto iTunes and register!
Itunes on the iPhone is preinstalled.
Sync your iPhone to iTunes on our computer
Apple only allows us to import iTunes to iPhone, not add iPhone to iTunes library. If you want to add your files from iPhone to iTunes, you have to use a third party program.
no you cannot use ipod and iphone apps on itunes, but you can buy the apps on itunes and put them on your ipod and iphone
you can't... but if you are doing this because of your iphone or ipod not syncing, you can update your phone to keep up with the new itunes
Plug in your iPhone. Connect to iTunes. Click Sync.
Normally when you register your handset, you also register for iTunes as well and you are normally provided with a prompt to download the latest version of iTunes. If this has not happened, then go to the iTunes website or search for iTunes using a search engine, then download iTunes and sign up for it that way, once your application has been launched after the download has been completed. You can also go to the iTunes website and sign up there without downloading iTunes to your computer but if you have an iDevice it's always best to download iTunes in any case.
