Since this is a cellphone forum I was wondering how many people have apps like Open Signal Maps, Sensorly or Cell Phone Coverage Maps installed on their phones. I've installed Sensorly recently on my Android phone and began reporting coverage for others. I think that if more people contributed there would be much less instances where one buys a phone only to find out that they have terrible coverage, it's also a good opportunity to see whether or not coverage has improved and whether 3G or 4G was added to an area. As we all know, the providers' maps aren't exactly known for their best accuracy and being updated often. So am I the only one?
