    oh you mean, i have to re-install the same baseband and re-jailbreak again and this will detect the simcard and the connection to my network will be OK...
    i'll try it and will tell you if it works...

    thank you again. :-)

    thank for your reply SUNDAR83,

    I think i'm confused,
    let me get it right, i have a 3gs version 4.1 with baseband 6.15.00 which cannot detect the SIM card saying NO SERVICE,
    you said i should just re-install and re-unlock and it will be OK...
    and then your next advise is to use ultrasnow fix 5.1... if my phone is in 4.1, should i upgrade it to 5.1 first and use ultrasnow fix? or i can use ultrasnow fix 5.1 even tho it's 4.1?

    i'm sorry for my ignorance, but I do really appreciate your tips and time to reply on my inquiries...

    thanks again SUNDAR83
