For iPhone 4/iPhone 3G S
Last update of Pwnage Tool & Redsn0w for iOS 4.3.3 left some important glitches for iPhone 4/3G S which have been fixed in the recent upgrade of the tools including the vibrator issue and battery drain improvements. Again, the credit goes to @i0n1c for the the bootrom exploit and figuring out these problems. If you have already used the previous version of either Pwnage tool or Redsn0w, all you just need to re-run the updated tools again by unchecking the cydia and check other needed options. This method is even safe for the ultrasn0w unlockers who preserved their BaseBand using custom firmware.
Note that only stock firmware can upgrade the BaseBand of your iPhone, thus making it non-functional against the software unlock. Redsn0w 0.9.6rc16 has some stability improvements too i.e Windows vista and Windows 7 users need not to set CPU affinity, just run redsn0w in XP compatibility mode. Also, the verbose boot option for iPhone 3G S old bootrom devices has been fixed for iOS 4.3.3. They can have custom bootlogos similar to other iDevices.
