hey there

i've done a few quick tests with a borrowed O2 3G-sim and ran into the
same problem.
BUT since this sim is from a gsm-geek we quickly tested a few things:
this sim had the pin set to 'off' (not asking, just do register) and the
FSO milestone1 which i used for testing still was asking me for a pin.
obviously the previously used pin was not accepted.
then we put the sim into another phone, set the pin from 'off' to '0000'
and swapped it back to the FR.
after booting FSO asked for a pin again, and this time it took the 0000
and registered fine. a quick call worked fine from that point on.

so: if your O2 3g sim does not want your (supposedly correct) pin, check
 if the pin is really needed with a second phone, and if not, set it to
0000 or so.
if this works for more people than just me, we might just have found a

ps: i have photos of the 'tricky' O2 sim, so if youre unsure or find
yours does the same, we should be able to identify the manufacturer by a
