Depends on your POV, I suppose- EVERY GSM handset ever built works with
the GSM tower locaation system. Sprint/Verizon had to force their
customer base to upgrade to GPS phones and now refuse to activate older
models in fear of breaking the 95%-enabled FCC requirement.

One of the advantages of GSM, at least in my opinion, is the ability of
the end user to choose any compatible equipment he wants, whether offered
by the carrier or not. AGPS added even more handset-chioce restrictions
to the already draconian US CDMA carriers.
