Before I alway flash with custom fireware and then unlock again,but now only can flash with 4.3.4 with itunes,what can I do,thanks.

put in DFU mode then restore to 4.1 and u gonna get "1015" error use tinyumbrella to kick out of recovery mode then just jailbreak and unlock

upgrade it to 4.3.4 and use this tutorial Tutorial: How to Unlock iPhone 3GS Running iOS 4.3.4 With UltraSn0w » Unlock iPhone
