Hi, I´m new here and I hope I´m writing in the right Place Please excuse my english, I hope you understand my Problem. The Problem is, that something went wrong during the JB and my iPhone 3G was on BB 06.15.00 but still on FW 4.0.1. Then I tried to update again to 4.2.1, iTunes did it, but in the middle of the update Process it told me that an update to an older Firmware is not possible. I know that it is because of the BB update. What I need to get my iPhone to work again is a custom 4.2.1 ipsw with 06.15.00 BB but I´m a Windows User and I don´t know anyone with a Mac. That´s why I´m asking if somone please could make a custom ios 4.2.1 with BB 06.15.00? It would be realy great!!! Thanks!!
