Does Cingular covers the Sidekick phone?

I want to purchase a Sidekick phone but I%26#39;m not sure if Cingular covers it.. Is it only T-Mobile? It would be great if I got some answers! =)

Thanks

Answers:

The Sidekick 3 is a T-Mobile Exclusive. Now actually you could get an "unlocked" phone then put your sim card in it but that actually defeats the whole purpose of the Sidekick because you would not be able to IM, have access to the internet, use the mP3 player, etc. It really sucks. I say either switch to T-Mobile or keep the phone you have. No it%26#39;s a T-Mobile exclusive.
