Greenpois0n doesn't hactivate your phone which is why you are stuck in emergency call screen. Do you have original sim card to activate the phone with? If not run Redsn0w 0.9.6rc8 for windows and it should hactivate your phone.

Do you need unlock? If you run redsnow you need the 4.2.1 stock firmware file and make sure you only choose the install Cydia option.

In addition to the above, yes you can safely use Redsnow after Greenpois0n. It doesn't collide and you don't have to re-run GP (considered it has run 100% ok the first time, which you currently can't test).

Then you're screwed for the moment. The update to 4.2.1 has updated your baseband to a version that is currently not unlockable, unless you've taken precautions (TinyUmbrella) prior to updating.

You can still use Redsnow 0.9.6 (whatever subversion) to hacktivate, but you won't be able to unlock it before a new Ultrasn0w version is released.
