Apple Posts New iOS 4.1 IPSW, SDK Betas - Developer News

Registered Apple Developers have been handed the second beta of iOS 4.1 and iOS SDK 4.1. Builds  885091b of iOS 4.1 and 10M2305a of iOS SDK 4.1 are available as free downloads from Apple’s iPhone Dev Center but only to those enrolled in the company’s $99-a-year iPhone Developer Program.

According to Apple, iOS SDK 4.1 beta 2 requires Mac OS X 10.6.4, while iOS 4.1 Beta 2 should only be installed on devices dedicated exclusively for iOS 4.1 beta testing. The iPhone maker advises developers not to install the software if they do not own a device dedicated exclusively to iOS 4.1 beta testing, going by a screenshot leaked to 9to5Mac (available above). Additionally, the company urges developers to note that iOS SDK 4.1 Beta 2, iOS 4.1 Beta 2, and Xcode 4 developer preview are pre-release software and are considered Apple Confidential Information.

Supported devices for iOS 4.1 Beta 2 IPSWs are iPhone 3G, iPhone 3GS, iPhone 4, iPod touch second generation, and iPod touch third generation. Developers are also advised to review the release notes and read me before installing iOS SDK 4.1 Beta 2. Specific changes are not revealed to the public. In leaking the information to the web, developers would break their NDA (non disclosure agreement) with Apple, although this is not unheard of.

Earlier this month, Softpedia reported that Apple had released the second preview of Xcode 4, a new version of the development tool for Mac OS X and iOS. Version 4 of the software combines Xcode with Interface Builder to streamline the development process of apps. Xcode 4 also brings a much cleaner interface, as well as "code-fixing," which allows the program to fix code errors as the developer types. Other areas touched by the second preview of Xcode 4 include LLVM Compiler 2.0, the Debugger, Fix-it, Instruments for Xcode 4, Assistant, and Version Editor.
