I too had a problem with mounts, and I am sure there are some great ones out there. But what I found that works for me is the Neoprene type armband case with velcro. Wrap that a few times around the center of the handlebars and it works great. I use cyclemeter as an app. I think its $5, and I love it. I am waiting for Pedal Brain, but I have been waiting for that for over a year.
