Situation

1) Downgraded 1.1.2 OTB to 1.1.1 jailbroken, tried hardware tutorial, failed at ienew
2) foolish enough to restore to 1.1.2, which failed with 1011
3) Finally I am at 1.0.2 using ibrickr (with BL 4.6 most probably)
4) No baseband, imei, iccid, wifi

Which is the right file to flash the baseband using bbupdater?
