Has anyone figured this issue out for sure yet? It seems to me that any 3GS that is less than 2 months or so old will get bricked when you try to flash the baseband. I have personally bricked 4...good news is any phone that new is still under warranty. One of the bricked phones was actually on 4.3.5 so I figured it was ok. They all will downgrade to 4.1 and jalibreak just fine but when you install the ipad bb it will cause loss of the wifi, bluetooth and modem addresses. I have tried using the newest versions of Redsnow and still get the same results. I even tried flashing the bb first before the downgrade...no dice.
