Bought this from a friend and was going to unlock it and give to my sister for t-mobile but my stupid friend updated the phone last night. I've unlocked may phones and still have the 2.2.1 quickpwn restore file (that has worked purfectly for restores in the past but it give me an errotrcode on wou't downgrade. I've placed it in DFU mode and still no go. Any advice or am i stuck until the 3.0 jailbrake/unlock comes out, thank in advance

Now, I'm not sure about this, but if you're feeling adventurous you could try disconnecting from the internet, deleting the 3.0 restore file, and restoring the phone.

But I don't know much about this, and it could be a horrible idea. Hopefully someone more knowledgeable will chime in here.

Oh, and it seems like people are speculating that the 3.0 tools will be here very soon, anyway.

PLENTY of articles out there on how to do this. Here is one of the top hits from Google:
http://crenk.com/downgrade-iphone-3g-30-back-to-221/

And here is the Google search results:
http://www.google.com/search?hl=en&...3.0+to+2.2.1+iPhone&btnG=Search&aq=f&oq=&aqi=

Just wait until tomorrow. You'll have a jailbreak and unlock for 3.0 anyway...
