Activation via DVD John's PAS (Phone Activation Server)

This method works by spoofing Apple's activation server. It is unclear at this point if this method works in both the Windows XP and Windows Vista versions of iTunes, and no information in available on porting this method to OS X. Details here.

Instructions step by step:
1). Download UltraEdit-32, install it.
2). Download PhoneActivationServerV1.0, extract it to desktop or anywhere you want.
3). You might wanna backup the original iTunes.exe(located under C:\Program Files\iTunes) first.
4). Run UltraEdit-32, open file iTunes.exe, use Ctrl+G to go to address 2048912, then enter 33C0C3. Do the same for the rest two offsets: Go to address 257074 then enter 28 and go to 257013 then enter 33C9B1. Save the file and close UltraEdit-32.
5). Open Windows explorer and go to c:\windows\system32\drivers\etc. Open the "hosts" file in ULTRAEDIT and add the line 127.0.0.1 albert.apple.comto it. This will redirect any DNS query of "albert.apple.com" to your local host. Save & exit.
6). All you need to do is to run Phone Activation Server V1.0 first, leave it running and then run iTunes. Now when you plug in your iphone it will activate automatically in about 60 seconds.
