hi the answer to the question is that you bricked the iphone and there is no way to fix it because i think u upgraded ur baseband tio ipad baseband 6.15.00 in order to unlock it but u should have checket the serial number of the phone before updating ur baseband. like for example: if ur serial 79013CDK3.... U SHOULD CHECK THE THE 3RD , 4TH AND 5TH DIGIT WHICH I THIS CASE IS 013 THAT MEANS THAT IPHONE WAS PRODUCED YEAR 2010 CORRESPONDS TO THE 3RD DIGIT CAUSE ITS A 0 ZERO AND THE 4TH AND THE 5TH DIGIT IS THE WEEK OF THE YEAR_, IN THESE CASE ITS OK TO UPDATE UR BASEBAND BUT IF UR IPHONE SERIAL SAYS 79135CDK.... THE ONE 135 IT MEANS 2011 WEEK 35 AD ITS A NO NO BECAUSE APPLE CHAD THE BASEBAND CHIPS TO TOSHIBA ONES SO IT WILL BRICK UR RADIO CHIP AND SO ON U WILL NOT HAVE A SIGNAL AN EMEI OR WIFI OR BLUETOOTH_, SO U CA USE IT JUST AS AN IPOD NOTHING ELSE JUST AN MP3 PLAYER THATS IT.
