I did have one ipad user that emailed complaining about the redirect, so the ipad was taken off the redirect list. I still like the redirect because I found that many people have troubles when they are instructed to add a “forward slash smartphone” after cavecountryweather.com. The “forward slash” gets them. 
As for those who might want access to the full content sometimes, there is a link on the bottom of the cell pages that goes to index2.php which is exactly the same as the index.php except it does not have the redirect script.
Looking at the page loads, a few people do use the cell page regularly. Rarely is the smartphone page viewed - like only 5 times that I can remember.
