    well… i actually have a german G1 phone (T-mobile) and tried to unlock it. Unfortunately it does not work, because after putting in a e.g. vodafone telephone card, the field for the unlock code does not pop up. Does anyone know, if it is necessary to first change the APN number to adjust for the new card ? Would i need a T-mobile phone card in the first place to do so ? If this is the case, i am screwed since i bought the phone through Ebay and it had apparently never been run with the initial T-mobile card.

    To anyone thinking about buying a G1 Phone there are lots of things that you have to consider… biggest is whether your service provider will support it.

    I have one myself, I am living in India. The phone is unlocked and working on Vodafone… well sort of…

    Though I can make/recieve calls, I dont have GPRS working. I am however able to access my email/android market/browse the internet via the wireless connection that comes with the phone (ie using my home computer wireless network to gain access to the internet).

    I now know that my GPRS plan does not support the G1 phone… I need to change my SIM to a better provider like Airtel and activate their Mobile Office GPRS package.

    Google G1 is a great phone, but there are some difficulties when setting it up. I wish I could work out all the kinks… sure I will get there eventually.

  • prashanna

    You can unlock your G1 to work for T-mobile or AT&T by simply entering unlock code on your G1 through keypad.
    You can get unlock code by G1 unlock code provider.
    I hope this helps.(
    Good Luck
