Apple has quietly updated the iPad version of the App Store for iOS with minor tweaks ahead of (and possibly in preparation for) the iPad 3 debut on Wednesday, AppleInsider reports. The changes mostly involve using more unhinted horizontal scrolling, which allows (for example) the Top Paid and Top Free iPad apps to be on screen in a more pleasing manner with more information available per app. Users can swipe each "list" to the left to see additional selections.
