Visual selection process and auto popup info button with ajax implemented

Click on the cell phone icon, there will be an in-line popup.

I used Graybox to do this. You can select the cell phone manufacturers on the left hand side, and choose your type of device in the middle frame. When the mouse hover the device image, product functionality and compatibility of the chosen device will be displayed on the right side under the device image.

All cell phone info is retrieved from database. After you selected the device, you will be linked back to the registration page and see which device you have chosen.
