Apple has announced that it is to end support for applications that were developed and compiled for its iOS 2.x.

As a push for adoption of the recently launched OS 4, has reported that the iOS developer newsfeed has encouraged developers to rebuild their apps in Xcode targeting iOS 3.x or later.

It said: “Make sure that your applications are compatible with iOS 4. All new applications and updates to existing applications must be built with iPhone SDK 4. In addition, the App Store will no longer support applications that target iOS 2.x.”

Apple released iOS 4 as a free update for all iPhone 3G, iPhone 3GS and the second and third generation iPod touch devices. The iOS is fully compatible with all of these devices with the exception of the iPhone 3G and second generation iPod touch, which do not support all of iOS 4's features.

According to the US Computer Emergency Response Team (US-CERT), iOS 4 was released to address multiple vulnerabilities across several packages that may have allowed an attacker to execute arbitrary code, cause a denial-of-service condition, disclose sensitive information, bypass security restrictions or conduct cross-site scripting attacks. It encouraged users and administrators to review Apple article HT4225 and update to iOS 4 as necessary to help mitigate the risks.

Earlier this year, Microsoft likened using Internet Explorer 6 to ‘drinking out of date milk' as part of an encouragement campaign for users to upgrade to IE8.

Meanwhile Absolute Software has announced its support for Apple iOS 4 products, including iPhone, to help IT departments within organisations to keep track of their devices. John Livingston, chairman and chief executive officer of Absolute, said that with enterprise deployments of devices on the rise, it was extending its focus on lifecycle management for Apple products to include the iPhone.

“With our forthcoming solution, IT will be able to address brand new challenges such as managing in-house applications and managing iOS device configuration,” he said. Slated for general availability during the summer of 2010, an updated version of Absolute Manage will provide IT departments managing iOS 4 devices with the ability to remotely manage aspects of lifecycle management and data protection.

According to Absolute, the lifecycle management features include the ability to remotely manage user profiles and provisioning profiles and gather device lifecycle management information from the devices. The data protection features include the ability for IT administrators to remotely send a device lock command or ‘clear passcode' command, or a ‘remote wipe' command to delete sensitive data from a missing or stolen device.
