Custom Radio Buttons & Date Picker Wheel

There are 2 tasks I'm looking to have completed. 1. Convert Custom Checkbox Script to Custom Radio Button Script (See attached file: [login to view URL]) This script works beautifully to create custom checkboxes. Could you please take the same script and modify it to work with radio buttons instead. Should be self explanatory once you look at the files, but let me know if you have questions. 2. Modify Spinning Wheel Date Picker Script for iPhone (See attached file: [login to view URL]) If you open the index file, you'll see I have instructions there on what I'm looking to do. I imagine the solution should be pretty simple and will only take a few minutes for someone who knows Javascript well, but I haven't been able to figure it out. Basically, I have a working script that creates a pop-up date picker wheel that emulates a native iPhone date picker. It works great as you can see in the file. The problem I'm having is I need it to work within an input tag on a form text field. I don't know what I need to do to get it to out put the result into the text field. Let me know if you have any questions. Thanks!
