Hello, I am new to the world of Smartphones, and I am completely amazed at what the Tilt can do. I have just one question.....inside the battery cover, there are what appears to be two antenna plugs. Are they both GPS Antennae or is one the actual phone antenna? I ask because there are a couple of areas of NY I travel to frequently where service is limited, at best. Is it possible to attach an external antenna to the Kaiser? ( I like that name better, it feels more "important" when I use it!
