    Hey guys i have a jail broken 3GS iphone previously with iOS 4.1 recently i upgraded to iOS 5.1 using itunes. I see the baseband has changed to 6.15.00 then i was not able to make my sim working, however this phone was not bought from a national carrier.

    Then i jailbreak using the redsn0w and chose the ipad baseband with the cydia installation when installed then again it didn't accept my sim. Used ultrasn0w and the ultrasn0w fix still no luck.

    Now i want to downgrade to the iOS 4.1 as i had already on my iphone using itunes i get the unknown error(20).

    And the iPhone is new bootroom.

    What to do now?? as the iPhone is useless now.. really frustrating. any ideas...

    You fried it. You're only option is to take it in and pray that they replace it.
