Hi there Just to confirm that my brand new out of the box iPhone with Firmware 1.1.1 and new baseband is fully working -> unlocked -> activated -> jailbraked with any SIM card (actually just tried Swisscom, but it works fine). First of all just following the manual of iNdependence for downgrading to 1.0.2, then activating, jailbraking and install ssh. After that just download the new iphonesimfree utility and register your IMEI number and unlock. After unlock you can upgrade back to 1.1.1 with independence and activating, jailbraking and install SSH again. After upgrade the SIM Card is fully working. Here is a good guide for this scenario: http://www.freeouriphones.com/MacTutorial.html For me only section 2 applied.
