After you’ve upgraded to iOS 5, you’ll probably discover that the developers of
your favorite apps have also released updated versions. If you want to check
whether you’re running the most current versions of the apps already installed on
your iPhone or iPad, you can do so wirelessly using a 3G or Wi-Fi connection.
From the Home Screen, tap on the App Store app, and then tap on the Updates
icon. If the message All Apps Are Up to Date is displayed, you’re in good shape;
otherwise, you’ll be given the option to upgrade any out-of-date apps.
After you initially acquire an app from the App Store, all subsequent updates to
that app are free of charge. Plus, now that you’re running iOS 5 on your device,
you’ll be able to easily share your app purchases among multiple iOS devices that
you own. For example, if you own an iPhone and an iPad, you’ll be able to purchase
an iPhone or hybrid iPhone/iPad app once and then install and use it on
both devices.
A hybrid app is one that is designed for use on both an iPhone and an iPad.
Some apps are iPad-specific, for example, and will run only on the iPad or iPad 2.
Meanwhile, apps designed specifically for the iPhone will run on iPads, but these
apps will not take advantage of the tablet’s larger display or advanced capabilities.
Although it’s often easier to update apps directly from the device itself, you can
also download app updates using your primary computer and iTunes, and then use
the iTunes sync process to transfer the updated app(s) to your iPhone and/or iPad.
WHAT’S NEW When you create an iCloud account and begin
using iCloud with your iPhone or iPad, all your app purchases (and free app downloads)
will be stored on iCloud. If you delete an app from your phone or tablet, you
can reinstall it anytime, free, from iCloud. When you return to the App Store, tap
on the Purchased icon that’s displayed at the bottom of the screen. All the apps
you’ve purchased (and the free apps you’ve downloaded) will be displayed. Tap on
the cloud icon displayed in each app’s description to reinstall it on your phone or
tablet.
