I apologize if this has been posted previously, but I have read a lot of threads on here and haven't seen it discussed. I live in an area of spotty 3G service and even with a bumper and a full body wrap, my dropped calls were exasperating. By turning off 3G and operating only on the edge network I haven't dropped a call in two weeks. I have wifi everywhere I use the phone the most so not having 3G isn't a problem for me. I do not accept this as a permanent solution, but at least for now I am able to use my phone. I know nothing of the technical details of what happens when you switch between a 3G tower and an edge tower, but it seems to me that this action could be improved with a "software fix" as previous phones that I have owned were able to compensate for the signals that are available in this area.
