    I have an Iphone 3GS model number MC135LL at firmware 3.0 and I am looking to upgrade it to 3.1.3 or 3.1.2.

    I used redsnOw to do my initial jailbreak, but that has been quite awhile ago and can't remember the process. If I just want to upgrade to a newer jailbroken firmware, what do I need? Do these programs work correctly on windows 7 64, or should I just pull out my old XP machine again?

    Thanks for any help.

    If it is still jailbroken then you can use a custom firmware by shift/restoring in iTunes. Download one or create one on a mac(pwnage tool) or Windows(Snowbreeze). Keep in mind though that Snowbreeze has been disastrous for many people.
