Thanks to the dedicated Dev Team for the iOS, we just heard that a small update to PwnageTool and redsnow has been released recently. The said update is said to be aimed at fixing the issue with the side vibration/ringer switch found in the iPhone 3GS and iPhone 4 models. The team wrote, ?If you?re already jailbroken at 4.3.3 (by either redsn0w rc15 or custom IPSW), you can install this fix simply by running redsn0w rc16 over your existing 4.3.3 jailbreak. Just uncheck the ?Install Cydia? option and check any other options you want. The fix will be installed no matter what you?ve selected. This is safe for even ultrasn0w unlockers to do (because redsn0w itself won?t update your baseband?only an iTunes stock IPSW update/restore will do that).?
