In iPhone OS Beta 3, there was a hint of a new feature that would presumably let a user change settings of the built-in App Store. With iPhone OS 3.0 Beta 4, seeded to developers earlier today, it has turned out to be a useful new feature: users can finally switch between multiple iTunes accounts within iPhone.
If you are someone who has multiple iTunes accounts, you’ve probably noticed how the App Store often gets confused about the number of updates available for download when it comes to over-the-air app updates; it may display an erroneous number of updates available, may fail to find any updates even when they are available, or may only display the number of updates for one or the other account. The only way to juggle multiple iTunes accounts is via iTunes on the desktop; you have to sign in to a particular account, get the updates for all the apps purchased with that account, sync your device, sign out, and repeat the steps for any other accounts.
With Beta 4, you’ll be able to easily switch between accounts from within the App Store or the iTunes Store on your device.
There is now a new “Sign In” button at the bottom of the Featured page in App Store. Apparently, you’ll be able to create a new iTunes account, though this does not seem to be working at the moment.
In Settings, the “Store” entry that was a placeholder in Beta 3, and which did nothing, has gained an icon and is now working. Tapping on it brings you to a page where you can sign in and out of an account or view account information.
If you choose “View Account”, you’ll be prompted to sign in once more, just like how it is when viewing account information in iTunes on the desktop.
Once you’ve done so, you’ll be presented with information such as your contact details and the balance remaining in your account. You will also be able to redeem gift codes from within this page, instead of having to find the “Redeem” button in the Downloads section of the built-in iTunes app, a step I have always felt to be rather counterintuitive.
