I have Tested this And,I still have that problem. I have updated to 4.3.3 preserving my baseband 01.59.00. And still have the i bar signal problem. Even before i jailbreak, i have the 1 signal bar issue.I have used Pwnage Tool, Snowbreeze, Red Snow,And Jailbreak ME.Com And all with the same results. The only way to fix the 1 signal bar problem is once you jailbreak 4.3.3 use Ultrasn0w Unlock, and you will get your signal bars back. BUT, If you are on a AT&T Network you start to have problems with mms, sending and receiving text. If you plan on using a different carrier you should be good. Remember the signal works just fine with the one bar, It is just cosmetic. I am staying on 4.2.1 for now.
