Apple is forcing developers to update, or otherwise pulling, applications offering a “Free Memory” function in an apparent attempt to ban the feature from the App Store. The “Free Memory” feature is most often a button found in iPhone and iPod touch activity monitoring programs such as Bjango’s iStat, allowing users to free up RAM that remains marked for use by closed programs. According to Bjango, iStat’s Free Memory function was removed at Apple’s request, and “all other apps with Free Memory appear to have been removed or updated without their Free Memory function.” It is unclear why Apple just now decided to outlaw the feature, or if the company plans on offering a similar built-in alternative, apart from simply restarting the device; users have long reported iPhone system and application instabilities traceable to memory problems.
