Just got a note from Apple that iPhone 3.1 SDK (beta) is up on dev center. So what’s new in this SDK?
• Organizer: the iPhone Development grouping now collects crash logs, install
bundles, and provisioning profiles in a single location
• iPhone OS 3.1 Simulator uses frameworks more closely matching the device
• Toolbar uses a single popup to choose platform, target, and debug/release
We are just getting started on 3.0 and not sure if a minor version upgrade is justified for these updates 🙂
You can read the full readme on dev center.
