Yeah no probs, it's good to give something back!!,
I had to do this, (copied and pasted from another site)
Step 1. Start > Programs > Accessories
Step 2. Run Notepad or WordPad
Step 3. Click Open.. from File menu.
Step 4. Browse to Windows/System32/drivers/etc
Step 5. In "files of type:" select all documents
Step 6. Open "hosts"
Step 7. Delete all line that has "gs.apple.com" or something like that
Step 8. Hit Save
Step 9. Restore your device
I followed that and the restore was successful, the only thing was I made a schoolboy error, I used appbackup, but didnt save that to my computer, so i'm gonna have to download a lot of stuff again, it's ok tho, it was just free stuff, and not much of it. Other than that no problem, I got the congrats message, and my mates sim works, so I'm definately unlocked, I'm going to Bangkok tomorrow so that's great news, no more using a crappy cheap handset while i'm there.
Thank's again, and as you say hopefully this will help out some of the less computer literate people like me!, lol
