As I mentioned in an earlier post, I have cancelled service with ATT and am considering switching to Cingular. I have two relatively new Nokia 3360s, which Cingular apparently would let me use. I called ATT but they say that they cannot give me any kind of code or assist me in "unlocking" the phones (according to Nokia customer service they should be able to do so). Are ATT just being obstructive? Can I "unlock" the phones myself? Or do I have to bite the bullet and buy two new 3360s from Cingular? Thank you.
You will most likely just to have to buy new Nokia 3360's however I think Cingular gives you those for free when you sign a two year contract and only $20-$40 on a one year for each of them. You shouldn't be out much money by getting new Nokia 3360's from Cingular.
AT&T is not being obstructive. That's just their policy. Sprint is the same way too. Sell them on Ebay and with that money buy one that is for Cingular. I used to have a Nokia 5160 and a Motorola Timeport both locked to AT&T and I activated them with Cingular and they worked perfectly even when they were still locked to AT&T and the display said "AT&T". My sister has another 5160 locked to AT&T too and it works with Cingular just fine in Pennsylvania. The phone even displays "Cingular" on the screen. See, their phones have to interoperate with both carriers because they share the network all over the US. Otherwise, you would not be able to get national coverage.
