when you registered the domain, you made it yours for whatever term you selected. You can legally transfer the registration to another registrar (see http://www.icann.org/transfers/policy-12jul04.htm), but registrars do limit when you can do that, i.e., in the time just before expiration. I've found it *much* easier to deal with the company that you want to transfer the domain to. A company losing business isn't as motivated to help you as a company potentially getting business.

The other issue is hosting though. New registrar or old registrar, you will still need to point the domain to a nameserver that identifies the machine where the site is hosted. So if the site is hosted with AT&T/yahoo too, you will either need to move the site to another server or continue to pay the cost of hosting the site there. The hosting charge should be billed separately from your ISP charge. (though it looks like the domain just redirects to the blog...is there any actual content on amiciveloci.org itself?)
