In an earlier blog, I asked should you upgrade to iOS4? Below are some reasons and advantages to upgrading. Keep in mind that iOS4 is compatible with the iPhone 3G, 3GS and iPod Touch and not all of the features are available for original iPhone 3G owners.
- Multitasking support for third-party apps
- Fast app switching
- Folders for grouping apps
- Bluetooth keyboard support
- Unified inbox in Mail
- App-level control over Location Services
- Home screen wallpapers
- App notifications that don’t require server connections
- iBooks support
If you agree that upgrading your OS is right for you, here are 5 easy steps you can follow:
Step 1: Update iTunes
To upgrade your iPhone or iPod Touch to Apple's iOS 4 firmware, make sure you're running the latest version of iTunes on your computer. After installation, you may need to restart your computer.
Step2: Connect Your Device
Once you've made sure iTunes is up to date, connect your iPhone or iPod Touch to your computer using the included USB cable. If iTunes doesn't launch automatically, you'll need to launch it manually.
Step 3: Select device
Once iTunes is open, and your device is connected, select your device in the iTunes sidebar so that the summary page (shown here) is visible. Take notice of the button for Check for Update but don't click it quite yet.
Step 4: Create back up
Just to be safe, make a backup of your settings prior to upgrading the firmware. To do this, right-click on the device icon in the iTunes sidebar and select Back Up. It should only take a minute to create a backup, and it's time well-spent. If anything goes awry during your iOS update, you can use this same menu to select the Restore from Backup option.
Step 5: Check for updates
Finally, click the Check for Update button from the device summary page. If your iPhone or iPod Touch is compatible with iOS 4, iTunes will tell you that an update is available for download and will guide you through the installation.
