Activating iPhone

If you already have a wireless account with the carrier, you may be able to upgrade your account to work with iPhone, or keep using your old phone and add a new line for iPhone. (Some accounts may not be upgradeable.) You may also be able to transfer your current phone number to iPhone, or get a new one.
For more information about iPhone, including videos about how to activate and use it, go to:www.apple.com/iphone
Inserting the iPhone SIM Card
In some regions, you may need to purchase the SIM card separately and insert it into iPhone before activation. Read the documentation that comes with the SIM card for instructions.
If your carrier gave you a PIN number to use with your SIM, you may need to enter the PIN before activating iPhone.
Activate iPhone
1 Download and install the latest version of iTunes from www.apple.com/itunes.
2 Connect iPhone to a USB 2.0 port on your Mac or PC using the dock and cable that
came with iPhone. Unless your keyboard has a high-powered USB 2.0 port, you must connect iPhone to a USB 2.0 port on your computer.
3 Follow the onscreen instructions in iTunes to activate iPhone and sync iPhone with
your contacts, calendars, email accounts, and bookmarks on your computer. A single checkmark in "Set Up Your iPhone" syncs all these items automatically. Or you can use iTunes to customize the information you sync, and to sync your ringtones, music, photos, podcasts, and videos to iPhone. See the following section.
You can disconnect iPhone from your computer after "Waiting for activation" appears on the iPhone screen. When activation is complete, "iPhone is activated" appears on the iPhone screen. This means that iPhone is fully functional and you can use all of its features.
Important: If you are migrating your current phone number to iPhone, activation may take from several hours to a day and migration of your number may take several days, depending on your location and previous carrier.
Syncing iPhone with Your Computer
When you connect iPhone to your computer, iTunes syncs iPhone with the information and media on your computer, according to how you've configured the iPhone sync settings in iTunes.
You can set iTunes to sync any or all of the following:
• Contacts - names, phone numbers, addresses, email addresses, and so on
• Calendars - appointments and events
• Email account settings
• Webpage bookmarks
• Ringtones
• Music and audiobooks
• Photos
• Podcasts
• Videos
Ringtones, music, audiobooks, podcasts, and video content are synced from your iTunes library. If you don't already have content in iTunes, the iTunes Store (available in some countries) makes it easy to purchase or subscribe to content and download it to iTunes. You can also add music to your iTunes library from your CDs. To learn about iTunes and the iTunes Store, open iTunes and choose Help > iTunes Help.
Contacts, calendars, webpage bookmarks, and photos are synced from applications on your computer, as described below. Contacts and calendars are synced both ways between your computer and iPhone. New entries or changes you make on iPhone are synced to your computer, and vice versa. Webpage bookmarks are also synced both ways.
Email account settings are only synced from your computer's email application to iPhone. This allows you to customize your email accounts on iPhone without affecting email account settings on your computer.

Have you tried to restart your computer and repeat the restore? And make sure that you have an excellent internet connection.

Do that first, if the error is still there, check if you have the latest version of iTunes on your computer. If not, update your iTunes by opening it and selecting "Help" from the menu bar then select "Check for Updates". After the update, do the restore again.

If you still get the error, follow my instruction on how to put your iPhone to DFU mode and restore.
