Apple currently upgrades the iPhone's operating system through iTunes each year. However, Apple started restricting the old version of iPhone in its latest upgrade, and even forbids the upgrade of the earliest version of the mobile phone.
Google mainly provides upgrades through operators and equipment manufacturers, which has led to users unable to switch to the latest version of the Android mobile operating system. Those users who had purchased their mobile phones a few months after the release of Android 2.2 had to wait longer to upgrade. In addition, the hardware requirements of the Android system continue to increase, resulting in the early users of Android phones can not use the latest version of the system. BlackBerry maker RIM is also facing similar problems when it comes to promoting BlackBerry OS 6.
Analysts are worried that with the aging Windows Phone 7 platform, Microsoft's strategy can maintain how long. According to the practices of other vendors, it is very likely that Microsoft will temporarily release those features that require high hardware.

Hub cards which are also installed in each cabinet of the LED display
