My first .app appears to be doing well on the iTunes store and it's all thanks to Nimblekit. It made the job easier, and without it I could not have achieved the end product in such a short space of time with my current skill. The .app was rejected at first as Apple classed it as a book, but I modified the .app on their advice and gained their support in version two to make the .app available.
One other thing worth a mention that I believe got me across the 'line' was Kristopher D Layon's eBook 'Create iPhone, iPod touch, and iPad Apps with Web Standards', and last but not least the support of other forum users here.
I do hope there will be a Nimblekit 2 as a standalone product as I have downloaded the Sencha stuff discussed elsewhere and it doesn't seem to offer the ease of access that Nimblekit does, but more learning ahead I am sure.
