Hi I have an unlocked phone and still on the legacy ATTWS charter
plan. The SIM I'm using is from 2002 and I believe is considered the
Old kind. I purchased a "newer" style SIM card 2 years ago and was
wondering if I would notice a difference in service if I called ATT
and had them change me from one SIM to the other? Is it true that the
older SIM only allows you to attach to a limited number of ATT/
Cingular towers or would it make no difference at all.

Thanks in advance
Sandro

It would probably make no difference, and probably can't be done in any
event, since I don't think AT&T/Cingular will now activate anything
other than a newer Cingular SIM.
