I've got an original Omnipoint SIM in my phone
which generally works fine, but is limited to a
modest number of phone number entries.

because of this, each time I store a new one it's
going into the phone memory rather than the SIM.

No great problem there, but I'd rather have them
all on that card so I could swap everything back
and forth into other phones (and also back it
up more easily).

So.. just to double check: If I get a newer SIM it'll
be able to hold many more names/phone numbers. Right?

Related question: how do I do this? will t-mobile
simply hand me a new one at a store (presumably
for some dollars, I'd guess)? And... would they
be set up to transfer the entries in the old
SIM to the new one?

Thanks
