There seems to be some good news for 3G users who had upgraded their ’s firmware to 2.2.1 sometime back and then couldnt unlock it back. The problem with 2.2.1 upgrade was that the baseband also got upgraded from 02.28.00 to 02.30.03 and with this baseband upgrade, 3G couldnt be used with any other SIM other than AT&T in US or Airtel/Vodafone in India.

Here is the good news – ModMyi is reporting that a tool called pHaseBanDowngrader has just been released allows 3G users to downgrade baseband from 02.30.03 to 02.28.00.

But this is not for Dummies, you got ot be a techie to downgrade your baseband. Here is how to downgrade:

  1. Download pHaseBanDowngrader from this address
  2. Connect via SSH to your
  3. Copy the downloaded folder (phasebandowngrader) into the folder “/Applications” on your .
    Note: The folder MUST named phasebandowngrader with lowercase letters!
  4. To run it, open MobileTerminal and type “login”. The user is “root” and password is “alpine” by default.
  5. Then type: “cd / Applications/phasebandowngrader/”, then, to run the downgrader, type “./phasebandowngrader”

NOTE OF CAUTION: This tool has been tested by multiple people and WILL NOT brick your device. if you have bootloader version 5.9 it will not work. you can try but it will not work (still no risk of brick). Use at our own risk, but there is really no risk of doing any damage to your device unless you do something absurd.
