Although we’ve been running iPhone OS 4 — right away well known as iOS 4 — given it was initial voiced in April, you actually haven’t been means to try out any of a fancy new multitasking facilities, since no third celebration apps have been released with await yet. That’s all about to change: as of today, Apple is usurpation iOS 4 apps, which means you should see utterly a few apps which take value of multitasking upon a iPhone 3GS as well as iPhone 4, as well as make make use of of the 1500 other brand-new APIs in a system when it launches upon June 21.

That’s really great headlines, but we’ve got the feeling Apple’s singular take upon iPhone multitasking will take a couple of people by surprise, as only sure tasks are authorised in the credentials — and apps that need to run steadfastly, similar to IRC and IM clients, still won’t really work at all. In actuality, there’s already a little rumblings by devs which they need additional backgrounding collection in order to yield facilities which users are asking for; Instapaper’s Marco Ament has proposed a network polling API which would concede his app to update calm in the background, for example. We’ll see how fast Apple responds to these requests, but for right right away we’re only happy we’ll finally be means to switch divided from the Skype call or GPS app whilst using our iPhones.
