I believe Tracfone's SIMs are rigged to prevent use in non-Tracfones, so
it's possible.

Again, you're thinking like a American CDMA operator- the GSM operators
just don't care if you choose a non-branded (or unlocked) handset. They
sell phone service- if having an unlocked, unbranded Nokia N95 makes you
happy, you'll be that much more likely to keep paying your monthly fees.
I'm sure T-Mo and AT&T have the ability to restrict the use of certain
handsets, but they seem to lack the desire.
