Unfortunately, the cellmapper.net site doesn't seem to work well on mobile devices. And when I try to use it on desktop, it doesn't work much better. And there don't seem to be any good cell mapper type apps on iOS. The only ones I've found are either specific to a particular tower owner, or they miss a lot of towers that I know are there, or they just don't work well. I've tried at least a half dozen, if not more. Are there any better solutions in this space?
