Is it possible to access your iTunes account via your iPad. that is log into your iTunes account, or is it only available via computer...... some people have only an iPad, so how do they access their iTunes account.....
For purchases, subscriptions, and other content management you use the Apple ID box on the bottom of the first tab in any iStore app. Tap on it for options.
If you are talking about your iCloud stuff, then there is no standard way to access icloud.com on the iPad. There are workarounds that will let you see the site, but not everything works as expected.
She since almost every iCloud service is tied to an app to or setting, this is normally not an issue. There are exceptions, of course.
