I was on 1.1.2, so I don't think it matters.
I didn't restore it to a newer firmware, the only restore I did was with the custom firmware.

You can start from any version, and no, it doesn't need to be restored before running Pwnage. I recommend cleaning off the content and 3rd party apps, but even that isn't really necessary.

Thanks for the great instructions. I was running 1.1.3 and was bit scared about upgrading but it was easy to do and I had no problems at all.

No, it is possible that Installer isn't even going to be available in the future, since it was produced by a company that is now very active on the AppStore. They may not produce a new version for FW2.0. However, Pwnage does let you install Cydia, which is a similar sort of thing. It doesn't have much content for 2.0 yet, but it does have Open SSH which will allow you to get into the phone and tinker with things.

When I restored mine with with the hacked firmware it restored ok, but wont allow me to put another sim card in only the card that was in it at the time it was unlocked etc. I have tried restoring it again without any sim card in it and it still wont recognise other sim cards, it just says "no sim" on the phone. Is there something I can to to fix this or should I have done something before I restored it with the hacked firmware.

By the way excellent instructions laughingbird made it very easy to get the 2.0 firmware running on my iphone, I had 1.0.2 firmware on it before and was a little worried I might turn it into an expensive paper weight with the other instructions that are around on the net.

Thanks for the great tutorial, I just successfully pwned my 2g iPhone FW2.0. See how it goes...

Thanks for the guide, it worked like a charm

Did the sim card that you had in the first time work? does it work now with original Sim.

Thanks for the guide - everything went swimmingly

Just one question, why when I now connect to my Mac, do I get a message "an update to the carrier settings is available. would you like to download it now"

iPhone 1g, FW 2.0, Optus sim.

I am with Telstra and got the same message, I hit yes with no ill effects. I am not sure what it does, although I discovered that my previously defunct voicemail button now works.

It just downloads and updates a property list with information specific to your carrier. You can go ahead and accept it with no ill effects.

Thankyou remhh and laughingbird - I can rest easy now.

After umming and arhing a week I finally following your guide and it worked a treat!

Got all contacts and sms's and everything back onto my phone. All functionality works as well.

On the whole I found this to be a really great guide and the whole process very easy.

Thanks Laughing Bird! You Rock.

For some reason I can't seem to download the bootloaders file at 3.3???

Have you tried downloading from the iclarified link posted in laughingbird's guide?
