Now that the problem with synchronizing app updates between the iPhone App Store application and the Mac’s iTunes application is cured with OS 2.1, it doesn’t matter which you use to update your iPhone applications. But I’ve found using the iPhone’s App Store application is more fun.
On iTunes, you can click the Applications item in the left column to see the iPhone applications you’ve downloaded. Near the bottom of the screen, you can click a link that checks to see is any of the apps have updates, and then you can download the updates. You can also click on one of the app icons that have updates to go to the app’s page in the App store. The description there will include a section that explains what changes are in the update.
In the App Store application on the iPhone itself, this whole thing seems more fun, is handier, and perhaps shows more informative. Touching the Updates tab at the bottom of the screen takes you to an update section that automatically checks the store for updates. Available updates are listed on the screen, and if you touch one, it goes to a special screen that shows you what is new in the update, without showing you the entire main screen for the app with its old information. And of course another touch and perhaps a password entry gets the update.
This seems more streamlined, and it all happens on the phone, wherever I am, without having to sync. I have a lot of apps on my phone, and it’s actually exciting to check a couple of times a day to see if anything new is coming in! Who’d have thunk it!
