    Default how to upgrade iphone 3G on 4.0.1 (05.13.04) to 4.1

    Hello,

    I have an iPhone 3G on 4.0.1 with 05.13.04 baseband, its jailbroken with jailbreakme.com and unlocked using ultrasnow.

    I want to upgrade it to OS 4.1, is there any way I can upgrade and can still jailbreak and unlock it again.

    Thanks in advance!
