Javascript - detect and redirect mobile devices

SMALL JOB - an Existing OSCommerce shop with mobile template has been updated and the mobile detect / redirect script needs an update. Let me know what you need to know. Probably quick work for anyone with OSC and mobile templates experience. The existing templates work....I just need them automated for correct presentation to smartphones and tablets. DELIVERABLE 1: .txt or .doc file written notes of the code and code changes and filenames. DELIVERABLE 2: code and code changes. I will be able to test by searching for the shop mobile layout from my smartphones. I will provide the main and mobile urls to interested Bidders in a separate note. Thank you, timepoor
