Hands On New 4G iPhone
What's new
• Front-facing video chat camera
• Improved regular back-camera (the lens is quite noticeably larger than the iPhone 3GS)
• Camera flash
• Micro-SIM instead of standard SIM (like the iPad)
• Improved display. It's unclear if it's the 960x640 display thrown around before—it certainly looks like it, with the "Connect to iTunes" screen displaying much higher resolution than on a 3GS.
• What looks to be a secondary mic for noise cancellation, at the top, next to the headphone jack
• Split buttons for volume
• Power, mute, and volume buttons are all metallic
What's changed
• The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic in order for the cell signal to poke through. Tapping on the back makes a more hollow and higher pitched sound compared to tapping on the glass on the front/screen, but that could just be the orientation of components inside making for a different sound
• An aluminum border going completely around the outside
• Slightly smaller screen than the 3GS (but seemingly higher resolution)
• Everything is more squared off
• 3 grams heavier
• 16% Larger battery
• Internals components are shrunken, miniaturized and reduced to make room for the larger battery
iPhone OS 4.0: The Best New Features
• Multitasking: It's here, finally. It's handled with a simple task switcher: double click your home button, and you get a list of running apps. Select, switch, done. Multitasking is limited to audio streaming, VoIP and GPS apps, as well as a few other allowances: they can finish specific, important tasks in the background, for example. As far as non-music/nav/VoIP apps, those can be suspended in the background, but not left running.
• Fast app switching: With iPhone 4's multitasking, most apps aren't actually running in the background—just certain functions of the app, like an audio stream or a GPS lock. But! All apps can now be frozen, in full, so that when you reopen them, they're restored to exactly the state they were in when they were closed.
• Local notifications: Notifications can be sent between apps on the phone, not just from remote servers. In other words, if something important happens in an app you've opened and moved away from, a notification will pop up in whatever app you're using at the time, effectively saying "switch back to me!" It's a fairly clever way to keep track of multiple apps without the need for a start bar or dock-type interface.
• App folders: Now you can sort your apps into folders! That's homescreen clutter solved, just like that.
• A new Mail app: Unified inboxes, multiple Exchange accounts, fast inbox switching, threaded messages: These new features are actually a huge deal, since the iPhone's mail client has barely changed since 2007, and Apple doesn't allow alternative mail apps.
• iBooks: Oh hey, that iBooks ebook reader app and accompanying ebook store we first met on the iPad has ambled on down to the iPhone. Nice, since you can now take your books with you wherever you go, as oppose to wherever you go with your iPad.
• Custom backgrounds: Jailbreakers have them. Hell, the iPad has them. Now you can choose a persistent background for your iPhone—and not just for the lockscreen.
• Game Center: Apple's going to roll out a centralized gaming service—a multiplayer network like PSN or Xbox Live—to help connect games to one another, by the end on the year. There are 3rd-party services that already do this, like OpenFeint. They will probably die.
• iAd advertising: It looks like Apple's finally making use of Quattro, that mobile ad company it gobbled up a few months ago, by rolling out its own advertising platform, a turnkey ad plugin for app developers called iAd. The theory here is that instead of relying on links to external websites, which pull users out of apps whenever they tap on an ad, developers can use Apple's new tools to keep people in the app while still showing them advertising—sort of like popover browser windows. You can watch videos, play games, and even buy apps from within these ads. This is in the iPhone OS 4 developer tools, but it's not explicitly a part of OS 4, so you won't see apps with iAds until later this year.
• 5x digital zoom: Could this hint at a higher quality camera in the next hardware? 3.2 megapixels seems a bit low for 5x digital zoom.
• Bluetooth keyboards: Another carryover from the iPad, Bluetooth keyboard support will finally come to iPhone 4.
