As @1L1keTurtles said, it's impossible for iP4 to have 6.15 baseband. To bypass activation screen without a carrier sim, hactivate by running redsn0w 9.14b2 ramdisk method jailbreak. No iP4 baseband cannot be downgraded. If you now have 4.11 or 4.12 baseband, only way to unlock is by official carrier unlocking.

  1. Do the set up. Press the Blue arrow to keep going to the activation screen.

  2. Once you are on the activation screen, press the home button to get to 'Emergency Call'

  3. Press Emergency Call.

  4. Dial '911' (Or whatever. I suggest you dial a number that is NOT an emergency number in your location)

  5. Press the Green button to make a call and QUICKLY press the power button to turn off the phone. (Don't slide to turn it off) Press cancel.

  6. Press 'Touch to Return to Call' at the top of the screen.

  7. Press Red button to End call.

Apparently some people think this will work. I deactivated my phone just to try it, but it activated almost instantly after boot, probably a CDMA thing.
