Step by step instructions
Find your UDID and activate it with the site in step 1
Open iTunes (the Mac or PC app, not iTunes on your iPhone).
Plug in your iPhone, iPod touch or iPad.
Click its name under the devices list.
Ensure you’re on the Summary tab.
Click on the text that says Serial Number. It should change to say Identifier (UDID).
Select Copy from the Edit menu.
Your UDID is now in the clipboard, so you can paste it into an email or message.
Open iTunes and upgrade to the iOS 7 Beta by choosing Restore.
1. Open iTunes and click your device on the left, go to summary tab at the top
2. Hold alt/option on Mac when you click Restore. Or on Windows, hold Shift when you click Restore.
3. Find the .ipsw file you downloaded and select it.
2. Complete the installation and then restore from backup if you desire.
*You can install old backup from before update - some phones don't need their UDID activated, but not activating your UDID can cause problems when Beta 2 is released or if you want to restore to 6.1.X*
*By the looks of it GSM phones doesn' need their UDID activated, but CDMA do, not 100% sure though*
