    I updated some apps in cydia(not sure of what they all were), I know for sure that one of them was ultrasn0w. After that I had no service. I am unlocked on 6.15 baseband and 4.1 firmware. It was originally on the Bell(canada) network, it has been unlocked on the rogers network now for a few month with no problems until now. It does say the carrier is rogers 8.0 but the network that usually says the same is now not available. Any ideas?

    Jailbreak your iPhone using yellosnOw, here are the steps for jailbreak iPhone 3GS.

    Points to be kept in mind
    1. Hacking iPhone could void warranty.
    2. Upgrade iPhone firmware 2.2, you should be aware that firmware2.2 breaks turbo sim.
    3. YellowsnOw doesn’t support pin enabled sim, so disable any pin you are having.
    4. Once your iPhone 3G is running firmware 2.2 with baseband firmware 02.28.00 is jailbroken, now you unlock iPhone 3g.

    I know you said your firmware is 4.1 but maybe this will work with that version as well.
    Some users faced a problem on iPhone 3gs and iPhone 4 after jailbreak iOS 4.3.1, the problem was No service after ultrasn0w 1.2 baseband 06.15.00 on iPhone 3GS and 01.59.00 baseband on iPhone 4. Now you can fix this problem by following the below steps.

    Step 1: Open Cydia on your iPhone 4 or 3GS
    Step 2: Go to Manage->Sources
    Step 3: Now tap on “Edit”, then tap on “Add”
    Enter the following repo

    Now tap on “Add Source”
    Step 4: Tap on Done.
    Step 5: Tap on and install
    Step 6: After the installation Go to again. Now scroll down and look for “Ultrasn0w fixer for 4.3.1” Tap on it. Install the package. It will ask you to reboot your device.
