I followed Geohot's method (needles trick requires a magnifying glass, dammit!) and everything seemed to work fine, right down to the point of seeing this out from minicom (which still shows it when I test);
I put in my TMobile SIM, deactivated (then rebooted), re-activated (then rebooted) with iASign web, but the phone complains that the SIM is locked and gives me a chance to enter a PIN to unlock with a scary "3 attempts remaining" warning.
Welcome to minicom 2.2

I know CommCenter is starting, since it's in the list and minicom won't run until I do a launchctl unload to get rid of it. But once I do, I can go into minicom and see that +CLCK: 0 thing.
The phone appears to be activated fine, since I can get around in the menus. But, of course, it also appears locked.
Any clues or next stabs I can take?
