If you have a great idea for an I-Phone web-ap but no knowledge about web design/SDK what should/can you do?K

I work in an industry where the I-Phone could potentially revolutionize almost every aspect of customer interaction & choice. I have had this idea for years & still no large player has come close to its implementation. The problem is i’m not a tech guy, but Steve Jobs presentation yesterday really got me thinking. Where is a good place for me to share these ideas?
