I posted the other night about being able to upgrade my phone now that
my contract is up, and was informed that i will be eligible.  however, i
have a few more questions regarding how cingular will deal with someone,
like me, who is on the old nation plan (w/o any roaming charges).  there
are a few scenarios i want to know about.

first, will i still be able to keep the old plan on a month to month
basis, or will they try to move me to one of the currently offered plan?

second, i assume that if a try to do the subsidized phone upgrade deal,
that will require extening the contract and moving to a new plan.  am i
right on that?

third, if i get a different phone from some other source,  (e-bay, i
suppose, although that scares the heck out of me), will they let me
switch to that phone without changing plans or extending the contract?

thanks for any responses.
