Unlikely that they will shut down the ATT network, except where the protocol
(e.g. GSM vs CDMA) AND the geographic coverage are identical.

It'll be alot easier to simply absorb the old ATT infrastructure, and simply
adjust their 'back-end' equipment to accomodate both frequency ranges.

Right, but you're still on AT&T's network behind the scenes, even though
it says Cingular in your display, from what they tell me. When they

anyway and the another is real low end, but the third is a Nokia 6820
which is pretty high-end. So I'm screwed I guess.

Can I unlock this 6820 so that it will work on Cingular? I saw that
online calculator someone mentioned but it doesn't have the 6820 on it.
After I unlock it, what do I do next? Is it out of service until I then
switch it over to Cingular? Do they just give me a new simm card or

Thanks for any help, have to do this in a hurry, like today/tomorrow
since the replacement for the one phone is supposed to be a birthday

My 6820 purchased through ATT is working fine on Cingular since the
