What do you mean with activation screen? On iPhone or in iTunes? On iPhone the Apple logo or the lock screen? If you restored your device to 4.2.1 without baseband protection and had 4.0.2 or lower installed, then you updated your baseband. This means you cannot unlock your device. To activate it, you need the original SIM anyway. Insert that (or from a friend) to activate your iPhone. Then check modem version. If it's higher than 1.59.00, you cannot unlock and need to wait for a new ultrasn0w release.
