For example, in the history of the iPhone 4 we talked about the new Retina Display, the updated camera, the glass and metal sandwich structure and so on.  But software can be as important as hardware, if not more.<\/p>\n<p>The iPhone 4 launched with iOS 4, which introduced FaceTime video calling paired with Apple&#8217;s first front camera.  However, the launch of iOS 4 has meant a lot to older iPhone owners as well, as it has made their devices much better.  In fact, iOS 4 could be one of the most important releases for the platform.<\/p><div id=\"forum-1311263905\" class=\"forum-content-2 forum-entity-placement\">\t\t<div class=\"ad-wrapper\" style=\"width:100%;min-height:250px;text-align:center\">\r\n\t\t\t<!-- In Article Blog -->\r\n\t\t\t<ins class=\"adsbygoogle\"\r\n\t\t\t\t style=\"display:block; text-align:center;\"\r\n\t\t\t\t data-ad-layout=\"in-article\"\r\n\t\t\t\t data-ad-format=\"fluid\"\r\n\t\t\t\t data-ad-client=\"ca-pub-3476569516614521\"\r\n\t\t\t\t data-ad-slot=\"9829044906\"><\/ins>\r\n\t\t\t<script>\r\n\t\t\t\t (adsbygoogle = window.adsbygoogle || []).push({});\r\n\t\t\t<\/script>\r\n\t\t<\/div><\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"inline-image\" width=\"1200\" height=\"1062\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" alt=\"Flashback: iOS 4 adds multitasking, FaceTime, and other important features\"><\/p>\n<p>First, we need to address the name.  The original software was called iPhone OS as that was all.  However, months after the original iPhone, Apple launched the iPod.  Then in 2010 came the iPad.  Then the software was renamed to iOS to cover all the iDevices it powered (Apple restored it a few years ago and we now have iPadOS, tvOS, etc.).<\/p>\n<p>Second, the introduction of multitasking was the biggest change to the platform since iPhone OS introduced the app store.  Of course, the way iOS 4 did it wasn&#8217;t true multitasking.  When you quit an app, it stops running.  The state of the app would be saved so that it can be restored when you go back, however, the app cannot do anything in the background.<\/p><div id=\"forum-38948137\" class=\"forum-content forum-entity-placement\">\t\t<div class=\"ad-wrapper\" style=\"width:100%;min-height:250px;text-align:center\">\r\n\t\t\t<!-- In Article Blog -->\r\n\t\t\t<ins class=\"adsbygoogle\"\r\n\t\t\t\t style=\"display:block; text-align:center;\"\r\n\t\t\t\t data-ad-layout=\"in-article\"\r\n\t\t\t\t data-ad-format=\"fluid\"\r\n\t\t\t\t data-ad-client=\"ca-pub-3476569516614521\"\r\n\t\t\t\t data-ad-slot=\"9829044906\"><\/ins>\r\n\t\t\t<script>\r\n\t\t\t\t (adsbygoogle = window.adsbygoogle || []).push({});\r\n\t\t\t<\/script>\r\n\t\t<\/div><\/div>\n<p>There were exceptions: some apps could perform some tasks.

However, apps such as Navigon&#8217;s MobileNavigator may continue to provide driving directions even if the app is not active, for example because you received a phone call.<\/p>\n<p>Multitasking was available on the then-new iPhone 4, the most powerful Apple phone ever made with its 1.0GHz Cortex-A8 CPU (ARMv7) and 512MB of RAM.  It was also enabled on the older iPhone 3GS (600MHz A8, 256MB RAM), but not the older models as they used ARMv6 CPU and only 128MB of RAM.<\/p>\n<p>The fast-growing Apple App Store has already had several hits that have entered pop culture.  To remember <i>angry Birds<\/i>, <i>Doodle jumps<\/i>, <i>Fruit Ninja<\/i>, <i>Cut the rope<\/i> and other?  But where to put all those apps?  Previous versions of iOS limited users to 180 screen shortcuts.<\/p>\n<p>The solution was obvious: folders.  This increased the limit to 2,160 apps.  The number of items on the home screen remained the same, 180, but each folder could hold up to 12 icons (no subfolders, though).  The newly created folders would automatically get a name based on the apps you entered into them (you could manually change the name later).<\/p>\n<p class=\"image-row clearfix\">\n<img decoding=\"async\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_617_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" height=\"240\" alt=\"A home screen folder\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_505_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" height=\"240\" alt=\"opening a folder\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_826_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" height=\"240\" alt=\"change a folder\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_49_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" height=\"240\" alt=\"change a folder\"><br \/>\n<br \/><span><strong>A home screen folder \u2022 opening a folder \u2022 editing a folder<\/strong><\/span><\/p>\n<p>Another new feature in &#8220;wait, couldn&#8217;t he do it before?&#8221;  the category is wallpapers.

The aspect ratio remained at 3: 2, but this laid the foundation for diversifying and improving displays on Apple devices (the iPhone 5 would bring a higher 16: 9 screen in 2012).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"inline-image\" width=\"727\" height=\"451\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_279_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" alt=\"Flashback: iOS 4 adds multitasking, FaceTime, and other important features\"><\/p>\n<p>We also mentioned FaceTime.  It was sold on the App Store as a $ 0.99 app &#8211; Apple wanted to offer it for free, but ran into some legal hurdles.  It initially only worked over Wi-Fi, but operation over 3G was enabled a year later.  FaceTime was joined by iMessage in 2011: Apple&#8217;s two exclusive communication channels are two of the tallest walls in its walled garden (the &#8220;green bubble&#8221; is a stigma).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"inline-image\" width=\"727\" height=\"584\" src=\"https:\/\/forum.sbenny.com\/blog\/wp-content\/uploads\/2022\/04\/1650771541_785_Flashback-iOS-4-adds-multitasking-FaceTime-and-other-important-features.jpg\" alt=\"Flashback: iOS 4 adds multitasking, FaceTime, and other important features\"><\/p>\n<p>iOS 4 has also improved the search.
