Updating to jailbreak iphone 3g

[rocketronnie]

Hi all i have a Iphone 3g that is jailbroken and is on firmware 3.12 i was wondering what jailbreak's is out for the most up to date firmware which i believe to be 4.2 that they stopped doing it?

Also is they any unlock's available for it if i update? Not that i would be to bothered atm just incase i want to make it easier to resell.

Cheer's !

You can use snowbreeze or pwnagetool to upgrade to iOS 4.2.1. Though the best option would be to keep your 3G on 3.1.3

Not to fussed about an unlock since i use it on the original tarriff, unless they is an unlock available?

whats your baseband or modem firmware version? and you can use sn0wbreeze to create a custom ipsw and update to 4.2.1

05.11.07 is my modem firmware.

perfect! you're covered by Ultrasn0w unlock. make sure you update using a custom ipsw created with pwnagetool or sn0wbreeze, that way you will not risk updating your baseband. then install Ultrsn0w and thats it.
