Updated jailbroken Iphone to 2.21 now locked please advise

Firstly let me start by saying hello fellow members & forum users, I am new here and am looking for help/advice, I have looked through the site yet probably being a newcomer still have not found exactly how to nail my problem.

I have been a pc user for 12yrs and last year made a great investment and bought mac book pro. I also have an Iphone (believe generation 2 thats around a year old) jail broke my phone about 6 months ago so I could get more out of it.

While I was away my partner was using it and seen the request for firmware update and so updated it to 2.2.1 :{


and so I now have a phone that is locked and when ever I triy to jailbreak it myself it just keeps bringing me back to either phone lock or Itunes restore where it asks for an .ipsw but cant locate it?
If I can get the help to make my phone work again I'd be really happy.




Thanks



If I manage to get it going again through help I receive here then I intend to donate $20-25 to the site.

from what I can gather things look bad as I was using a payg sim which is no longer accepted which means I cannot use either the phone or its utilities and may be stuck until their is a fix posted.


Thank you.


ps I have tried to jail break on the mac using pwnage 2.5 pwntool 2.2 it seemed to work until the final restart when it just went back into locked mode.
I can prove it is my phone as I have copies of texts emails sent from it up until a few days ago,,,,

You have a 2G silver backed phone right?

If so put it in DFU mode, restore with to 2.2.1 again then try Quickpwn

Here is a good guide with all the links for the needed software etc
