I am happy to report the the PwnageTool worked out great and was very easy. I am now on 4.3.1 (YES!) and have my original baseband. Now I went into Cydia and ran ultrasn0w and it did its thing. I rebooted and I am not staring at 1 bar with no carrier name. I read that for some who ran ultrasn0w BEFORE the recent update, they were still able to make calls, etc even with the 1 bar (no carrier). For me though I cant do anything. In fact I dont even seem to have options for to look into my settings under cellular data network. Any ideas?
