Answer 1

Not that the firmware you downloaded to restore was a custom which does not change the BB? 

 

If this release for ultrasn0w, that BB gives many problems in iOS 6.X. I would lower the BB to 05.13 to unlock with ultrasn0w.

Answer 2

   You must restore with redn0w, baseband to change that, as the world gives all operating problems.

 Sim card  not recognised  indicates that your phone is locked with your current network . Make sure that your phone accept other network mobilesim cards. If no, you need to unlock it from your servcie provider or from any of the online vendors like  TheUnlockSpot.com   to unlock it . After unlocking your phone, you can use any other sim cards with it .
