  1. i have downloaded the file iPhone3,1_4.3.1_8G4_Restore.ipsw
    but its a zip folder and couldn't find the file with .ipsw extention ?
    am i doing things correctly
    please help

  2. I have iPhone 4 with 4.1 bb02.10.04, does it mean i need to upgrade to 4.3 (with new baseband) and then jailbreak & unlock? The phone has so far never been jailbroken or unlocked

    • you can use redsn0w 0.9.6b6 if you want to jailbreak 4.1, there's no software unlock available for your baseband, but you can use Gevey Turbo SIM (click iPhone4 unlock above)

  3. I have an iPhone 3GS already on 4.3.1 with baseband 5.16.02 and need an unlock – should I go ahead use redsn0w to jailbreak & upgrade to 6.15.00 for an unlock?

  4. Hello, I have and iPhone 4, 4.2.1, bb 03.10.01. What I have to do for jailbreak and unlock my iPhone. Do I have to upgrade to 4.3.1 and then use redsnow 0.9.6rc9? How i unlock if ultrasnow does not work yet? Please help

  5. Hi, I'm at 4.2.1 with baseband 6.15 and consequently the no GPS issue. When do you suggest I update with the new redsnow to get my GPS working? Do you know if it fixes the GPS problem?

  6. I have iPhone 3GS Version 4.3 BB 5.16.01. I read about the GPS issue with 4.3 and 6.15bb so i havent flashed my phone yet to 6.15……Should I just update to 4.3.1 and use redsn0w 0.9.6rc9 and ultrasnow to jailbreak and unlock my phone? Would I still have GPS problem then?
