I ran into a bit of an issue last night. I needed to upgrade from iPhones OS SDK 3.0 to 3.1.3 (I hadn't because I hadn't had a need in the past 8 months). Well, upon trying to use Appcelerator I discovered that it requires the iPhone SDK to be >3.0… alright, head on over to apple but alas… there’s no way to download 3.1.3! Doesn't it figure, I’m still running Leopard, and 3.2 is Snow Leopard ONLY. Pft. So, after much searching I finally managed to find a download link for the iPhone SDK 3.1.3.
Download iPhone SDK 3.1.3 and Xcode 3.1.4 – last verified 9-10-10
