The front camera, meanwhile, is designed for Apple’s new strike at the video calling market, something many others have attempted to kick-start and have had, for the most part, little success. Called FaceTime, the new app is currently exclusive to the iPhone 4, and is neatly integrated into the standard apps.There are a few provisos, as you might imagine for a new system, and which if it weren’t for Apple’s market appeal we might question FaceTime’s likelihood of success.First off is that you’ll need a WiFi network in order for FaceTime to work, since right now Apple won’t let video calls be made over cellular connections. Tapping the FaceTime button in Contacts starts a video call straight away, or you can switch from a regular cellular voice call to FaceTime midway through (though not, it’s worth noting, in the other direction). That seems to be a decision based on network bandwidth, with Apple giving the carriers time to get their systems up to scratch; Steve Jobs hinted that the 3G situation may be reconsidered in 2011, though it’s possible that Apple could build in carrier opt-out as we’ve seen them do with tethering
Second, the person you’re calling will have to have an iPhone 4 themselves, since so far FaceTime only works on that one handset. While defaulting to the front-facing camera, you can toggle between that and the rear camera – though not at the full 5-megapixel resolution – to show your surroundings, and FaceTime works in both landscape and portrait orientations.In practice, the FaceTime experience feels a lot like iChat on the desktop – or, indeed, like video calling in Europe or Asia where the functionality has been available, cross-platform, for years now – with the screen dominated by the person you’re talking to and your own face in a PIP inset in the top corner. Image quality was reasonable over a broad WiFi connection, though when we tried using a MiFi-style mobile 3G router as a bridge we did notice some visual artifacts breaking in. We’re more than a little confused why Apple didn’t build in iChat desktop support, though, which would’ve instantly made the iPhone 4 more appealing as part of an existing ecosystem. Apple are opening up the APIs in the hope that other companies will pick them up and build in compatibility to their own devices, but that, again, will likely take some time. Of course, with record-breaking numbers of iPhone 4 pre-orders over the past week or so – and no sign of demand slowing down – there’s a good chance you may know someone out there with one of their own, so that compatibility question may not apply.
The iPhone 4′s other headline software features have, ironically, been scooped by the iOS4 update Apple pushed out to the iPhone 3GS (and, less so, the 3G and iPod touch) late last week. The new version of iOS brings with it Apple’s answer to some of the more persistent criticisms of its mobile range, including multitasking support and a unified inbox, and if you’re a 3GS owner who finds iOS4′s feature list satisfies most complaints you have with your cellphone, you might find trying out the (free) update for a while saves you the cost of upgrading to the iPhone 4.As you might expect, given Apple’s vocal objection to multitasking in previous years, iOS4 handles multiple apps somewhat differently to how rival platforms approach it. Their argument has been that battery life suffers to an unacceptable degree when software is running in the background; hence on the iPhone 4 background apps aren’t in fact operational but are frozen in the state you left them. In effect it’s a type of caching, packaged with a handful of new APIs that developers can take advantage of. Those APIs allow for background audio, such as in streaming media apps like Pandora, to continue, as well as task completion, where uploads or syncs are finished even if you switch away from the app before it’s doneThe new caching and APIs are packaged together with an app switching dialog that, when you double-press the home button, pops up at the bottom of the display and allows you to flick between recently used titles. Of course there’s also the existing push notification system that triggers pop-ups when server-linked apps have a new update.. It works well, overall, though the biggest drawback is that none of the new multitasking functionality is native; apps must be coded specially to take advantage of the APIs and of the caching. There’s also background GPS, which keeps navigation-centric apps updated with positioning data, and background VoIP, which allows apps such as Skype to stay on the look out for new incoming calls without having to be active all the timeWithout that support, the software will show up in the app switcher but you’ll be back to square one each time you return to it.
