10 Useful Links about the iPhone OS 3.0 Preview for Developers
Today, Apple held an iPhone OS 3.0 Preview event for developers and the press. The upgrade itself won’t be available to end users until summer so as a developer you’re looking at a minimum 3 month lead time to develop updates and new products based around the new features. This hasn’t stopped the blogosphere going [...]
Cocos2d (Open Source 2D Engine for iPhone) Gets Key Updates
Back in December we posted about Cocos2D, a 2D graphics development framework for the iPhone (and Python, if you prefer).

Some Brutally Honest iPhone App Sales Numbers: $32k Spent vs $535 Revenue
Owen Goss is the developer of Dapple, a cute color matching puzzle game for the iPhone (you may also remember his memory leaks tutorial here on Mobile Orchard).

A Giant List of iPhone Developer Related Links
Ari Braginsky (a.k.a. lemonkey) has been busy putting together a frankly intimidating list of links to resources that iPhone developers will appreciate.

Skip The Humor in your App Store Descriptions; Apple Doesn’t Like It
Never Odd or Even LLP – a UK-based development shop – decided to get all funny when submitting their Instant New York app to the iTunes App Store.

It’s Here.. an iPhone Simulator for Windows

Pinch Analytics is designed to help you see how users use your iPhone apps and see your download numbers in real time.

656 iPhone Developers to Follow on Twitter – Add Yourself Too!
Whether you use it or not, you’ve probably heard of Twitter – ostensibly a social networking tool where you let people know what you’re doing but, ultimately, far deeper than that (that description is like describing e-mail as “a way to send words to people”). There are lots of iPhone developers on Twitter and a [...]
