    Default Upgrade 3g from 3.0.1 and keep jailbreak?
    I have an iphone 3g running 3.0.1. It has cydia and quickPWN on. Can I upgrade somehow to 3.1.2 or 3 and keep the jailbreak? On itunes it just says that this firmware is not supported. Thanks.

    Yes, you can. Read this link , it will explain to you how you can restore to 3.1.3 , jailbreak with Redsn0w 0.9.4. After the jailbreak , you can go to Cydia and unlock with Ultrasn0w.
    http://modmyi.com/guides/how-jailbreak-3-1-3-iphone-3g-ipod-touch-1g-2g-windows-os-x/

    OR You can download SnowBreeze 1.5.2 and create a custom firmware of 3.1.3 and then restore to it. Once restored, you are already jailbroken and as usual, install Ultrasn0w to unlock.

    I have used redsnow before - i have 0.9.3 saved. Just read the link and noticed the following paragraph:-

    "Next order of business is for iPhone 3G users. DO NOT Upgrade to 3.1.3 or follow this guide if you need an unlock. Upgrading to 3.1.3 will upgrade your baseband which is not currently unockable."

    Is this before ultrasn0w, as I definately need it unlocked? Also would i be correct that I substitute upgrade to OS4 for 3.1.3 as itunes will only ug to os4 now?

    Sorry for all the questions but I have a buyer for my phone but it needs to be unlocked and a newer os, and I don't want to mess it up.

    sorry, do I need to use fuzzyband aswell?

    Upgrade to iOS 4 thru iTunes and use Redsn0w 0.9.5b-5 then unlock with Ultrasn0w via Cydia.

    To reduce lag on iOS 4, disable wallpaper and multitask when Redsn0w prompts it.

    Be sure to use the latest version of redsn0w. You can get ultrasn0w thru Cydia by searching it, it should already be in there.

    Hi Annie thanks for all the help. I've now got IOS4 on. I just did the jb and all seemed to go fine then the phone turned off, and didn't come back on, so I turned it on manually and there was no cydia. I used redsn0w 0.9.5b5-1. I know there is now 5b5-5 but I couldn't find a download. I'll try again to find it but if you have any more ideas I'd be grateful. Thanks.

    Managed to get the right version of redsn0w, then had the ios4 version conflict. After numerous downloads I found a compaible one and now have cydia!!!! Have just downloaded ultrasn0w for the unlock but can't be sure it works as i don't have a different sim to try so will have to wait until tomorrow. Thanks for your help.
