I am either a sheep heading into slaughter or a newbie entering an exciting challenge. I would like to create a relatively simple application for iPhones. The complexity of which would probably increase as time went on and I became more proficient. Where do I start and how do I go about getting my app in the iTunes app store - it is intended to be a free app, but my solicite donations for a non profit group - would that be OK??? Also, is there a book out there called, "Developing Apps In Sencha For Dummies" or the like?
