    I have an jailbroken iPhone 3G 3.0 Baseband 04.26.08. I downloaded and installed ultrasn0w but it still shows NO SERVICE. Any help is appreciated, ty.

  • John

    OK, ran redsn0w ok, confused by the instruction above where it says to “add Cydia installer” as it was there after redsn0w, right?

    Anyway, neither Cydia or Icy will get ultrasn0w for me so I am stuck with no service for now…..

    Is there any other way known to run ultrasn0w as I have internet via Safari and wireless?

  • john

    if you use ultrasn0w to unlock open cydia .manage>source>edit>add then type repo666.ultasn0w.com only if using a jailbroken phone

    if you use purplerain to jailbreak i think this is the better for the 3gs never has crashed for me do the sae as above only add apt.geohot.com to your sources then run it will unlock phone from your phone

  • John

    Yes, I have done this 100 times “if you use ultrasn0w to unlock open cydia .manage>source>edit>add then type repo666.ultasn0w.com only if using a jailbroken phone”

    CYDIA or ICY just will not get the file for me – I think it is “proxy” problem, will let you know in a few days when I get back to civilization.

    Phone must be jail-broken because I have CYDIA, right?

  • John

    YAH !! got it, CYDIA website must have been unavailable for me, but when it did connect, downloaded a lot of updates, then able to ultrasn0w, no problem, now have ex-Aussie iPhone working on Saudi Arabia MOBILY network !!!
