For example, given my phone number 801 555 1517, is there a way for someone to learn that I use Cingular? Why do I ask? Well, I have free minutes when calling other Cingular users, and I'd like a way to vet my phone list for Cingular users. tag:ask.metafilter.com,2005:site.19679 Wed, 08 Jun 2005 16:23:06 -0800 cellular mobile number phone provider reverse-lookup service silusGROK
