Hi All,


I am using iphone 3gs with IOS 4.1 with modem firmware 6.15 . Now i want to know whether i can upgrade it to 4.3.3 ? If Yes how?

Please advice me...

You can update to 4.33 only if you have your SHSH saved? Have you used Tinyumbrella before to save the shsh? Anyway you can check if you have the shsh saved for 4.3.3 with tiny umbrella or with the last redsn0w 0.9.9b7. Let me know if it worked, if not I can try to do it for you online, just send me a PM
