| If I buy an unlocked phone to use in Europe with a Sim I buy there, can I
use a cingular or other domestic Sim card here and keep the phone unlocked.
In other words will the US carrier lock my phone if I use their service.

Yes.

No, that's not how locking is accomplished.

Once a phone is unlocked you can use any network, it won't get locked again.
Note your phone will need to be 1800/900 for virtually all countries outside
the USA.

Once it is unlocked it stays unlocked.

No. The only phones that are locked are the ones the carriers sell.
You can put any SIM in any unlocked phone and it will work. Sim
Locking or SP lock is something that has be done specifically prior to
sale of the phone.

Very interesting! One of the reasons I chose NOT to go with Cingular
was because I was bringing our unlocked phones from our former carrier
(a regional that didn't lock their phones), their people told me that
once I installed a Cingular SIM, the network would lock the phone. I
asked how they could justify that, given that I'd brought the phone TO
them - didn't buy it from them. I own it. And if I wanted to leave
Cingular, I would then have a locked phone. He said that's just
Cingular's policy to keep people from switching. End of sale!

A Cingular SIM will prevent many phones from manually choosing another
carrier once they are camped on a Cingular tower. That may be what the CSR
meant. That does not prevent you from using a SIM from another carrier and
using THEIR network.

Sorry, but that's total BS. It simply cannot be done.
