  1. I added the url for ultrasn0w in Cydia, but the screen is stuck on Updating Sources and Downloading Packages. I’ve tried rebooting it several times but no success. Any advice?

  2. I got my iPhone unlocked … But just wanted to tell that when you are unlocking and you don’t have carrier information nor you have any other internet connectivity on your iPhone .. try Cyder which is a desktop application and can install applications on Cydia using the windows desktop …

  3. Dears my iPhone 3GS 3.1.3 5.12.01 dont boot.

  6. Jailbroken with Redsn0w OS 4.0. Unlocked with Ultrasn0w. Shows service but will lose service almost right away. I don’t know what else to do I have tried everything. Any suggestions?

  7. i successfully unlocked and jailbroke my fone to the 4.0 OS but now my internet does not work unless im connected to wifi and i have no mms. is this any way to enter these settings?

  8. This upgrade worked perfectly, now I don’t have 3G data active now, all networks work fine for the phone but not for data so now I have lost my work email and cannot connect to the network, any help would be great

  9. Hi Guys,

    Very similar to everyone i too hold a IPHONE
    3gs 3.1.3(7e18) with Modem firm ware 5.12.01. I bought this directly from apple store and not from any grey market.

    the method really encouraging however can any one tell me
    what are things which one should NOT do before unlocking.

    I have already done the Jailbreak using Spiritji. However im little tensed to unlock. After reading all the posts the success % is high and people who have not unlocked is very less.

    But please share What things that one Should NOT do before unlocking.
    eg: like a only AT &T sim should be there and not any other carrier sim before unlocking.

    Steps required please.

  13. If the cydia is hanging at updating resources
    use Cyder -desktop application- instead
    It will work perfectly :)

  14. I also added the url for ultrasn0w in Cydia, but the screen is stuck on Updating Sources and Downloading Packages. I’ve tried rebooting it several times but no success. Any advice?

  15. THANK YOU! You are wonderful. Even though there were some error messages it still unlocked it perfectly. FYI, I had to use redsn0w 9.2 first on my 3G with a 3.0 OS and 05-13-04 baseband.
