    DON'T !!! You have the best configuration possible for 3G: upgrade to 4.x.x will slow down your device without saying it will lock it permanently (unless you are ready to loose GPS). You can use a custom firmware to save your BB but you'll still have slow down and in my case battery drain too.

    If you're really want to update firmware, make sure you preserve your modem baseband 5.11.07

    1. Make sure you save SHSH with tinyumbrella first, so you can go back to the firmware that was saved.

    2. Use sn0wbreeze 2.7.3 to build custom firmware for 4.3.3, search forum or internet to learn how to do it. (make sure: DON'T put a check mark on unlock with iPad baseband 6.15.00)

    Note: If you don't have original carrier sim, put a check mark on "hacktivation" option.

    Your iPhone will be on firmware 4.3.3 with modem firmware 5.11.07 and is jailbroken.

    3. To unlock it, install ultrasn0w from cydia and it will be done.

    Read more and make sure that you know what you're doing, if not you may end up with unlockable modem baseband.

    Good luck.

    Have you read carefully? he has 3G, he can't upgrade higher than 4.2.1 and tinyumbrella doesn't save shsh for firmwares lower than 4xx (there's no need for it anyway)
