Forget the iPad here comes iPhone OS 4

With the iPad dominating the news this weekend, what with the first units being delivered and then quickly jailbroken, you might think that there could be little in the tech world to upstage it, at least in terms of media frenzy, for a few days. However, it would appear that a press event set for April 8th is set to do just that. The surprising thing being that it's being held by Apple itself.

According to Engadget Apple is holding an invitation only press event at the Infinite Loop campus in Cupertino on the 8th. The invitation speaks of a 'sneak peek' at the 'next generation iPhone OS software' no less. Yes, it's iPhone OS 4 already! This could be fun, given that leaked reports at AppleInsider of proper multitasking coming in iPhone OS 4 have been doing the rounds recently.

Although, as we understand it, this is just an early teaser of what to expect, it does seem likely that Apple will want to get proper multitasking onto the iPad as soon as possible and OS 4 is the route to doing that. Indeed, perhaps this press event should come as no real surprise as it is really about the iPad after all - the iPhone just happens to run on the same OS.

flagged the right story — this OS preview is less about a gadget headline and more about changing the app lifecycle and developer workflow. Apple is delivering a tightly controlled set of background services so third‑party apps can continue selected work while the system manages battery and foreground performance. (apple.com)

Practical checklist for app teams:

  • Treat backgrounding as a state transition: save user data and prepare a clean UI snapshot in the methods the OS calls when an app leaves the foreground; restore state on return. (scribd.com)
  • For short “finish what I started” work (uploads, DB flush), use the OS background‑task APIs so the system grants a finite run window; always balance start/end calls. For continuous services (audio, VoIP, location) declare the appropriate background mode and use the matching frameworks. (scribd.com)
  • Avoid trying to run arbitrary long tasks in background — design around server‑side work, push notifications, or brief background tasks instead. (scribd.com)

App‑store and UX notes:

  • Expose obvious settings when an app will keep doing work while not frontmost (playback, location tracking). Be explicit in release notes about what runs in background and why; this helps set expectations and reduce support issues. The platform is built to preserve battery by limiting background activity, so opt in only when justified. (apple.com)

Testing and validation:

  • Test on real devices across OS versions and conditions (low memory, poor network). Use Instruments’ Energy/CPU/network traces to spot hidden drains and verify the app behaves correctly when suspended, resumed, or terminated. (audentia-gestion.fr)

Bottom line: treat the preview as an API/behavior change that requires lifecycle, energy, and UX work — the result will be smoother apps on both iPhone and iPad when the final release arrives.
