I have had my iPhone3G for three and a half weeks now. For the first two and a half weeks, I only had EDGE service throughout my house. About a week ago, I was surprised to notice for the first time that I had one bar of 3G on one side of my house. This morning, I noticed two bars of 3G in some spots of my house and one bar of 3G in most of my house. Has anyone else noticed new 3G coverage in an area that previously only had EDGE? Note: sometimes the 3G signal cuts out and it switches back to EDGE. The transition takes about 5 seconds. I live in Southern California, USA.
