Custom Development on iPad or iPhones

Hi All,

What is the infrastruture need to start developing SAP Mobile apps on an iPhone or iPad. By Infrastruture i mean IDE's, Plugins, Licensing etc. I would like to build this app using the existing SAP Mobile Infrastructure(not SUP).

How do I start off? Is there any documentation/Blog that could help in this respect?

Any help would be hugely appreciated..

Thanks & Regards,

Johannes.
