Why no iPhone 3G? Apple abjectly refuses to put their name on an implementation where hardware constrains software - see video recording last year - and that means iPhone 3G isn't up to their multitasking standards.Īs to how it works, instead of a traditional 'leave full apps running in the background' approach, Apple instead chose to implement a more restricted but, they felt, better performing and power friendly solution involving 7 specific background API (application programming interfaces.) (At least for iPhone 4 and last year's iPhone 3GS). four years, many gripes, and stiffer Google Android competition than later, background multitasking comes to App Store apps. While Apple's built-in apps (like iPod, Mail, etc.) have had background multitasking since 1.0. (We're not counting getting a resolution bump for iPhone 4 Retina Display as a functional change.)

Calculator: Upgraded back in 2.0 for landscape scientific mode, all Calculator gets this time is a slight icon tweak towards the red.

Clock: With nothing but a lap feature added last time, we lose the 'but' and keep the 'nothing' for iOS 4.

Voice Memo: Introduced in iPhone 3.0, it looks pretty much the same in iOS 4.

Not even a Calendar-style icon update to show current local weather.

Still no HTC TouchFlo 3D style animations, no landscape mode with more/different information. Weather: Almost comedically at this point, it's still unchanged from iPhone 1.0.Stocks: Similarly, Stocks got landscape and a slew of swipe-able data last time, so the update love gets skipped this time.For more information on any functionality that's pretty much identical to past versions, check out our previous walkthroughs:Īnd here's a quick list of the unchanged apps in iOS 4:

As always, we'll start off by telling you what hasn't change so we can clear the deck for what has.
