Hello, world! I'm glad of thinking of being an iPhone developer, but I have some fire-queries, hope you turn it off; I know how to code in JavaSciprt, HTML5, CSS3, so: 1- Can I make an iPhone app using that languages? 2- If yes: can I use Python with MySQL as server-side languages? 3- How much time it needs to learn Objective-C and iOS SDK from zero to professional? 4- Is there a difference in quality between making apps using Objective-C and other languages? 5- How did Evernote make their app's UI? I've noticed a very different UI form the old version! As you can see here: http://d.pr/i/I67O Actually, I've noticed a huge difference in UIs last year! What happend? Is it HTML5 techs? or new GUI in Xcode? Thanks in advance!
