OpenLayers + PhoneGap + JQuery

http://ozmin.es is written using OpenLayers, JQuery, and JQueryUI.

It was easy to have http://ozmin.es as iPad or iPhone app using PhoneGap,

where the difficult thing is to setup PhoneGap to know where iOS SDK is!

The next step is to investigate JQuery Mobile on iPad and iPhone and also Android and maybe Windows 7 Phone
