    Hey y'all,

    I have an iPhone 4 on 4.2.1, jailbroken via greenpoison.

    I want to update to 4.3 (willing to lose all jailbreak), but I am a tad bit worried about the update process.

    Do I just click the update button in iTunes?

    I did use Tinyumbrella before, so I already edited the hosts back to normal.

    Thanks!

    OP, can you pls post if your baseband was updated? Did you try to preserve it by keeping tinyumbrella in the background?

    If you search around you will find a few people who got errors because of a HOSTS line that the last iTunes upgrade did not change.

    They've got around the problem by manually deleting the line in HOSTS that was pointing to the wrong server.
