I just wanted to let you know that your blog post on this topic was the most useful place I found information about SIM services in the USA. I live overseas and I'm visiting the US for a short time and wanted a cell phone...way too much information out there with all these people trying to sell you something sketchy...your information was right on the money. I'm going to go to a Cingular store tomorrow and get one of their pre-paid cards. I find their plan better for me with what I'll be using my phone for while I'm here.
