Jailbreak your iPhone

Unlock iPhone 3G OS 3.0 Baseband 04.26.08 with UltraSn0w


As promised Musclenerd showcased the next version of QuickPwn and UltraSn0w. Yes UltraSn0w replaced the YellowSn0w for iPhone 2G, 3G with OS 3.0 DevTeam will release UltraSn0w for iPhone 3G on iPhone OS 3.0 firmware with baseband 04.26.08 on Friday. For unlocking your iPhone 3G with UltraSn0w it doesn’t matter which baseband or bootloader your firmware is running on. Now iPhone 3G is unlocked up to the latest Baseband. Now you needn’t to follow those lengthy procedures to downgrade baseband but limited to Bootloader 5.08 Downgrade iPhone 3G Baseband from 4.26 to 2.28 & Downgrade Baseband 02.30.03 to 02.28.00.

UltraSn0w works same as YellowSn0w. About UltraSn0w application is a small daemon that is launched on boot.  It injects the payload at boot and also whenever there is a baseband reset.  You won’t notice anything about it other than that your third-party sim now works.  It’s a small program and unobtrusive. The UltraSn0w unlock will be released on Friday 19th along with iPhone 3G S and will be applied in the same manner as the previous yellowsn0w unlock. The procedure will work on the 4.26.08 baseband version so all those who accidentally updated to the latest baseband will be able to regain their unlock. And anyone at 3.0 FW or below will be able to use it.

For iPhone 2G unlocking wait for Friday or if you are in a real hurry then use our simple but lengthy trick here Unlock iPhone 2G OS 3.0 7A341 Final Version.

    hi i have a factory 3.0.1 3gs with firmwire 04.26.08

    i have jailbreaked my phone and i have installed ultrasnow.

    when i reboot phone and install sim it shows reception but says sim not supported.

    i cannot reload 3.0.1 and jailbreak again as itunes does allow me to, it will only let me upgrade to 3.1.

    Any ideas?

    I have been trying to get this working on my iPhone 3G for the past 2 hours but it keeps on failing with the No Service message.

    I have tried jailbreak using Pwnage Tool (mac) and Redsn0w and then installing ultrasn0w via cydia but after restart i keep on getting greeted by this ‘no service’ message.

    I have tried this 4 times now.

    Hey Vinay, I don’t want to get my hopes up, but does this mean my iPhone 3G w/ 2.2.1 w/ Baseband 2.30.03 & BOOTLOADER 5.9 can be unlocked? The man concern I have is the bootloader! Please let me know 🙂

    Hi there, im using 3g with 2.30… and bootloader 5.9. will ultrasn0w unlock my phone for any carrier (voda)? will i be able to finally get rid of my turbo sim and jailbreak with no hassle?? Regards

  21. Bassrawee June 21, 2009 Reply

    unlock will give you Cydia annd Installer and other programs. you can purchase more programs and Icon from places that much cheaper the Apple.
    once you jailbreak you Iphone you will see Cidya and Cydia connect to the Internet via WiFi and you will list of so many programs, freeware and shareware. if you need programs and “Icons” you need to jailbreak your phone, however that won’t affect your AT&T services (as far as the current software, but that may change in the future_ one thing you put in mind that jailbreak will canncel your warranty services from ATT and Apple.

    hope that help
