Sn0wbreeze Released for iOS 4

The folks over at iH8sn0w have been hard at work updating sn0wbreeze to work with iOS 4. They finally have a release ready, and it will jailbreak iPhone 3G, iPhone 3GS (old bootrom), and iPod Touch 2G (old bootrom) on iOS 4. This obviously won’t work for devices that don’t support iOS4, and will not jailbreak devices with new bootrom.

sn0wbreeze is a tool for Windows® that will jailbreak your iPods and iPhones, setup custom boot logos, activate your iPhone, root partition size, build custom IPSW, and more!

This is similar to The iPhone Dev Team’s Pwnage Tool for Mac, (in fact it uses a lot of the same coding), but brings that functionality to Windows. Same rules apply, for iPhone 3GS; you must be already jailbroken on previous firmware to install a custom iOS4 firmware.

    There is no public exploit for the new bootrom, so we have no idea when. If you want to keep your jailbreak, don't update.

    Hi, I've never jailbreak my iphone 3GS before.. it's with oldboot rom.. so can I still use this?

  • rorypiper

    Downgrade to OS 3.1.2, then jailbreak with redsn0w. Then you will be able to install a custom iOS4 ipsw.

    Help. I can't seem to figure out the ipsw file. i have downloaded it as a zip file and the extract the files then what? Can't find the ispw file. Please help someone
    Thanks, Bruno

  • rorypiper

    What browser are you using to dowload? The ipsw should not download as a zip file. The ipsw is a compressed package, and your browser might be detecting it as a zip file. Just download it in iTunes, so you know you have the correct file.

    I am using Explorer. Mine is already jailbroken with blackrain ,iso3.1.2. Should I go and do the firmware upgrade with itunes and then jailbreak using sn0wbreeze. I usually can figure this out but I am stuck, how do i download the ipsw file with itunes?(no laughing :)
    Thanks Bruno

    I was just replying to your email! It sounds like you're iPhone is good to go. Jailbroken on 3.1.2 with blackra1n is fine. Just plug your iPhone in to your computer, iTunes will ask if you want to update… Download and Install or Download Only. Click download only. Search for your “iPhone Software Updates” folder, to fond your firmware.

    Hey Rorypiper, thanks for your help. I will try it. What could go wrong? :) I am to assume I would use sb0wbreeze after to jail break it? If you have a moment maybe you could email me step by step instructions to You have been very helpful.
