Apple Seeds iPhone OS 3.0 Beta 3 and New SDK to Developers

185718 iphone 3

Apple today seeded the third beta version of iPhone OS 3.0, along with a new build of the software development kit (SDK), to developers. World of Apple republishes the seed notes for the SDK, detailing a number of changes to various components, including Xcode, Interface Builder, and Dashcode, and notes that applications targeting pre-OS 3.0 devices are unable to be tested on the latest beta.

Apple has this evening released beta 3 (build 7A280f) of iPhone OS 3.0 due for release in the Summer.

Of note in the latest seed is that Apple advises developers, "Applications targeting devices prior to iPhone OS 3.0 beta cannot be tested in this seed. This bug is intended to be fixed in a future seed."

Changes to the iPhone OS 3.0 beta 3 will not become apparent at first.

No visible changes in the new version of the OS have yet been detailed. The last beta was seeded to developers on March 31st.

RIP, MacBook Ultra

Monday October 19, 2026 9:37 am PDT by
Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...
