| Apple iOS4 Review & Walkthrough |
| iOS4's release from Apple is upon us and is the fourth version (4.0) of the Apple iPhone/iPad/iPod Touch operating system. Back on April 8 at a preview event, Apple showed off 7 new major features added to iOS4 and promised a total of over 100 new features in total. Some of the major new features include multitasking, home screen customization, and application folder creation. This review of iOS4 is meant to show you the features added to iOS4 that we consider to be "major" and ones that most users will notice with casual use. These screenshots (and the basic content of the review) were based off the iOS4 Gold Master (GM) release from WWDC 2010, but it should be almost identical to the final version which will release on June 21. If anything changes or differs, we will be sure to update this review.
Spell Check & Replace Spell check has finally been brought to the iPhone & iPod Touch (the iPad already has it) with iOS4. When iOS4 thinks you have misspelled a word, it underlines it with red just like a word processor and tapping on that word will give a popup with recommended correctly spelled words. Tapping on the word you want will replace it automatically. iOS4 continues to include Apple's powerful predictive auto-correct text suggestions and corrections as well.
 The familiar cut, copy, paste popup also gets a new addition in iOS4, the "replace..." button. This will allow you to replace an auto-corrected word with the original word if it isn't what you originally intended. This is useful when you're typing something that isn't in the OS's database and it changes it when it really shouldn't. Wi-Fi Devices can now stay connected to a Wi-Fi network while in sleep mode, which means any applications that require an Internet connection will continue to work even with the device in sleep mode. Bluetooth Keyboard Support iOS4 allows users to wirelessly connect a hardware keyboard via Bluetooth, which will make for easy input of lengthy text or Web chatting. The Home Screen Users have been complaining for a while now about not being able to change the default gray background of their home screen. Jailbroken device users have enjoyed this ability for some time, but now legit users can do it too. The new default background in iOS4 is waterdrops on a gray gradient background, but you can change it to one of the many new included backgrounds or one of your own in your camera roll.
 The top bar's status area in the upper left corner now shows more status icons, including a northeast-pointing arrow when you're using location-based services (GPS), orientation lock (more on this later), and the usual Bluetooth, clock, and battery icon (and percentage if you choose). Also, a colored bar will appear underneath the top status bar when you're engaged in active voice or data connections. The color green indications an active voice call, blue for Internet tethering (more on that this later), and red for a voice memo or VoIP connection. Multitasking Multitasking has been brought to iOS4 for the iPhone 4, 3GS, and 3rd Generation iPod Touch. Only these devices are supported because Apple has deemed their hardware capable of the "power" required for multitasking. Apple designed iOS4 multitasking very carefully and didn't just choose to allow full applications running in the background as this would reduce performance and battery life. Rather they took a more refined approach and allowed a more restricted application of multitasking that falls into seven categories.
iPhone 1.0 had only one home screen that didn't allow for much room for applications, but there wasn't any App Store back then. iPhone 3.0 allowed for 11 pages of apps and a maximum of 180 viewable applications. iOS4 now allows for the creation of folders right on the home screen. Each folder can now hold up to 12 applications, which means a device can now hold up to 2016 applications. To create a folder, just tap and hold an icon to make them wiggle, then drag it over top of another icon and it will create a folder. The OS will then take a look at the category data for the applications and try to come up with an appropriate name. It does a fairly decent job of making names, but sometimes it doesn't. If the name it made doesn't work, you can edit it to whatever you want.  To open a folder, just tap it on the home screen and the background (and other icons) become translucent and gray, leaving your open folder front and center. To remove an application from a folder, make them wiggle like before and just drag them out. A folder will delete itself when there is only one application left inside. The new iPhone 4's will come with a folder named "Utilities" and will contain the Clock, Calculator, Compass, and Voice Memos applications, but any iPhone user can simply make the same folder if you want to hide these less frequently used Apple applications (as you still cannot remove them). Photos  Photos, for Mac users with iPhoto 09, get the ability to organize photos by Events, Faces, and Places. (Windows users only get Places). For the users with iPhone 09, you can let Photos automatically file away your pictures by date/time (Events), through facial-recognition (Faces), and geographic location (Places). These new views are shown across a bottom tabbed bar in the Photos application. Also, the Camera Roll gallery can now be viewed in landscape mode for better photo viewing. Another new feature is the ability to reduce image file sizes when e-mailing by allowing iOS4 to scale down your pictures prior to attaching them. It typically gives you just a few choices out of the available, Actual Size, Small, Medium, and Large, depending upon the original size of your photo.  Messages (SMS) The SMS Messaging application in iOS4 now has built-in Spotlight search along the top. There is also a character counter that appears when you've hit a second line of text during an SMS message to see how many of the 160 characters you've used and if additional texts will be required. This feature has to be turned on from the Messages area of the Settings application.
Nothing much has changed here in terms of functionality and features, but there is a new icon for activating location-based services (aka: GPS and/or cellular triangulation) that matches the one that shows in the top status area.
 In iPhone 3.0, Apple introduced Tap to Focus for taking photos, but in iOS4, it now applies to video recording as well (for the iPhone 3GS & 4). Also now in both iPhone models is the ability to zoom using a 5x digital zoom. Activating the zoom is simple, just tap the screen and a slider appears along the bottom allowing you to drag the slider to zoom in and out. The zoom quality isn't too bad actually, but does require a steady hand for any decently-sharp picture to be taken.If you're using the iPhone 4, there is a button to allow you to switch from the 5 megapixel backside camera to the frontside VGA camera. There is also an icon to enable/disable the flash. |

Widgets: Sliding to the left while on the first page of running apps in the multitasking dock will show the new widgets pane. Here you can lock the screen orientation to portrait, which will not allow the screen to rotate to landscape mode. When the screen is locked, a lock icon will appear in the top status bar. From the widgets pane you can control the music that is currently playing on your device, with the playback controls (skip ahead, skip backward, and play/pause) and the ability to pull up the application that's playing music (ie: iTunes, iPod App, Pandora, etc.). The current song title (if content is playing) appears under these controls as well.
